OHAUS TDS

OHAUS is a manufacturer of weighing instruments and laboratory equipment with a history dating to 1907 in New Jersey, United States. The company's product portfolio includes balances, scales, moisture analyzers, and a line of portable water-quality meters. The OHAUS TDS series consists of pocket-sized total dissolved solids meters designed for field and benchtop measurement of dissolved solids concentration in water and aqueous solutions. These meters are used in applications such as hydroponics, aquaculture, drinking water testing, and industrial process water monitoring. The TDS series includes models with different measurement ranges and accuracy specifications. For example, the ST10T-A and ST20T-A offer a range of 0 mg/L to 100 mg/L, while the ST10T-B and ST20T-B cover 0 mg/L to 1,000 mg/L. Accuracy is specified as ±2.5% full scale for the ST10T models and ±1.5% full scale for the ST20T models. The ST20T versions include automatic temperature compensation from 5°C to 40°C (50°F to 104°F) with a temperature resolution of 1°C and accuracy of ±0.5°C. These meters are pocket-sized, battery-operated, and intended for direct immersion of the sensor in the sample. 3G Electric supplies the OHAUS TDS line as part of its industrial equipment distribution portfolio. The company provides access to multiple SKUs, including the ST10T-A, ST10T-B, ST20T-A, and ST20T-B, with logistics support for global delivery. 3G Electric serves plant engineers, maintenance managers, and procurement specialists who require portable TDS measurement for water quality checks, process control, and compliance monitoring. The OHAUS TDS meters are suitable for routine measurements where a handheld, single-purpose instrument is preferred over a larger benchtop analyzer. The meters are typically used in agriculture, water treatment, food and beverage production, and educational laboratories. 3G Electric's role is to make these instruments available through a streamlined procurement process, with product specifications and part numbers clearly identified to support accurate selection. The company does not manufacture the OHAUS TDS meters but distributes them as part of a broader range of industrial and laboratory equipment. For technical buyers, the key selection criteria among the OHAUS TDS models are measurement range, accuracy, and the presence of automatic temperature compensation. The ST10T series provides basic TDS measurement with ±2.5% FS accuracy, while the ST20T series offers improved accuracy of ±1.5% FS and automatic temperature compensation. All models are pocket-sized and designed for single-hand operation. The meters are powered by replaceable batteries and include a sensor that can be rinsed between measurements. Calibration is typically performed using standard TDS solutions, and the meters may include push-button calibration or automatic recognition of calibration standards depending on the model. The OHAUS TDS line is part of a broader OHAUS water quality portfolio that also includes pH and conductivity meters. This allows users to standardize on a single brand for multiple water-testing parameters. 3G Electric supports the OHAUS TDS line by maintaining inventory of multiple SKUs and providing logistics coordination for international shipments. The company's catalog includes detailed specifications for each model, enabling buyers to compare range, accuracy, and temperature compensation features. For procurement specialists, 3G Electric offers a single point of contact for OHAUS TDS meters and related industrial equipment, reducing the number of suppliers required for water quality instrumentation. The OHAUS TDS meters are not intended for continuous inline monitoring or for high-temperature or high-pressure processes. They are portable instruments for spot checks and field measurements. Users should verify chemical compatibility of the sensor with the sample before use. The meters are typically calibrated with standard solutions and require periodic recalibration according to the manufacturer's recommendations. 3G Electric provides access to these meters without regional restrictions, serving customers worldwide. The company's focus is on supplying the specified product with accurate part numbers and timely delivery. Technical support for calibration, maintenance, and troubleshooting is available through OHAUS documentation and authorized service channels. 3G Electric does not provide calibration services but can facilitate access to replacement sensors and batteries where applicable. The OHAUS TDS series is a practical choice for applications requiring a compact, battery-operated meter for measuring total dissolved solids in water. The range of models allows users to select the appropriate measurement range and accuracy for their specific application. 3G Electric's distribution of these meters supports plant engineers, maintenance managers, and procurement specialists in obtaining the instruments needed for water quality testing and process control.

The ST20T series is suitable for applications requiring tighter accuracy and temperature compensation.

What is the measurement range of the OHAUS ST10T-B pocket TDS meter?

The OHAUS ST10T-B pocket TDS meter has a measurement range of 0 mg/L to 1,000 mg/L total dissolved solids. Its accuracy is specified as ±2.5% full scale. This model is part of the ST10T series, which does not include automatic temperature compensation. The ST10T-B is a digital, pocket-sized meter intended for field measurements of TDS in water samples. It is suitable for applications where a range up to 1,000 mg/L is required, such as hydroponics, aquaculture, and general water quality testing. The meter is battery-operated and designed for direct immersion of the sensor.

Does the OHAUS ST20T-A include automatic temperature compensation?

Yes, the OHAUS ST20T-A includes automatic temperature compensation. The temperature range for compensation is 5°C to 40°C (50°F to 104°F), with a temperature resolution of 1°C and accuracy of ±0.5°C. This feature adjusts the TDS reading based on the sample temperature, improving measurement consistency when samples vary in temperature. The ST20T-A has a TDS range of 0 mg/L to 100 mg/L and an accuracy of ±1.5% full scale. It is a pocket-sized, digital, auto-ranging meter suitable for water quality testing in applications such as drinking water, hydroponics, and industrial process water.

What are typical applications for OHAUS TDS pocket meters?

OHAUS TDS pocket meters are used for measuring total dissolved solids in water across various applications. Common uses include hydroponics and aquaculture to monitor nutrient or salt levels, drinking water testing to assess water quality, and industrial process water monitoring to check for dissolved solids that may affect processes or equipment. They are also used in educational laboratories for teaching water analysis. The pocket-sized, battery-operated design makes them suitable for field measurements and spot checks. The choice between models depends on the required measurement range and accuracy. For example, the ST20T series offers higher accuracy and automatic temperature compensation, making it suitable for applications where temperature variation is a concern.

How do I calibrate an OHAUS ST10T or ST20T TDS meter?

Calibration procedures for OHAUS ST10T and ST20T TDS meters are specified in the user manual provided by OHAUS. Typically, calibration involves using a standard TDS solution of known concentration. The meter may have a push-button calibration function or automatic recognition of calibration standards, depending on the model. It is recommended to calibrate the meter before critical measurements and at regular intervals according to the manufacturer's instructions. The sensor should be rinsed with distilled water between measurements and before calibration. For specific calibration steps, refer to the OHAUS documentation for your model. 3G Electric does not provide calibration services but can supply the meters with the appropriate documentation.

What is the accuracy specification of the OHAUS ST20T-B TDS meter?

The OHAUS ST20T-B TDS meter has an accuracy specification of ±1.5% full scale. It has a measurement range of 0 mg/L to 1,000 mg/L total dissolved solids. The meter includes automatic temperature compensation from 5°C to 40°C (50°F to 104°F) with a temperature resolution of 1°C and accuracy of ±0.5°C. It is a digital, auto-ranging pocket meter. The ST20T-B is suitable for applications requiring a wider measurement range up to 1,000 mg/L with better accuracy than the ST10T series. It is used in water quality testing, hydroponics, aquaculture, and industrial process water monitoring.
