Frequently asked questions
Common questions about OHAUS from 3G Electric.
What is the difference between the OHAUS ST10C and ST20C pocket conductivity testers?
The OHAUS ST10C and ST20C series differ in accuracy and measurement range. The ST10C models offer ±2.5% full scale accuracy, while the ST20C models provide ±1.5% full scale accuracy. For example, the ST10C-A measures 0 to 199.9 µS/cm with ±2.5% FS, whereas the ST20C-A covers the same range with ±1.5% FS. The ST20C series also includes models with higher ranges, such as the ST20C-C, which measures up to 19.99 mS/cm. All models operate on four AG13 batteries and require separate electrodes. Selection depends on the required accuracy and conductivity range for the specific application.
What are the specifications of the OHAUS AX2202 precision lab balance?
The OHAUS AX2202 is a precision lab balance with a capacity of 2,200 g and a readability of 0.01 g. It features a VGA touchscreen display and an ABS housing. Repeatability is 0.01 g. The balance is designed for general laboratory use, including sample preparation, quality control, and routine weighing tasks. It is a benchtop unit, and its compact design allows it to fit in standard laboratory workspaces. The manufacturer part number is AX2202. For detailed operating instructions and calibration procedures, refer to the product documentation provided by OHAUS.
What is the OHAUS CLR-RODA015 support rod used for?
The OHAUS CLR-RODA015 is an aluminum support rod designed for laboratory use. It has a 1/2-inch rod diameter and a 6-inch overall length, with a 1-inch overall height. This rod is used to hold clamps, burettes, and other apparatus in general lab setups. It is part of a modular system that includes clamps and other support hardware. The aluminum construction provides a balance of strength and weight. The rod is compatible with standard laboratory clamps and can be mounted on a base or attached to a frame. It is a component in assembling experimental apparatus where stable positioning of glassware or instruments is required.
What are the power requirements for OHAUS pocket conductivity testers?
OHAUS pocket conductivity testers, including the ST10C and ST20C series, operate on four AG13 batteries. These batteries are included with the tester. The testers are designed for portable use, allowing field measurements without access to external power. The battery life depends on usage frequency and operating conditions. When the batteries are depleted, they can be replaced with standard AG13 cells. The testers do not include electrodes or reagents, which must be purchased separately. For specific battery life information, refer to the product manual. The use of AG13 batteries makes the testers convenient for on-site water quality testing and other field applications.
What materials are used in OHAUS lab clamps like the CLM-MULTI2SZM?
The OHAUS CLM-MULTI2SZM lab clamp is constructed from zinc with a nickel-plated finish. It features 2 prongs, a 3/8-inch arm diameter, and an overall length of 8 1/2 inches. The nickel plating provides corrosion resistance and durability. This clamp is designed to hold apparatus such as wire supports and other laboratory equipment. The single adjust clamp design allows for secure positioning. The zinc construction offers strength while maintaining a relatively low weight. This clamp is part of the OHAUS line of laboratory support hardware, which includes rods, clamps, and other accessories for building stable experimental setups.
Can OHAUS pocket conductivity testers measure high-conductivity solutions?
Yes, certain OHAUS pocket conductivity testers are designed for higher conductivity ranges. The ST20C-C model measures from 0 mS/cm to 19.99 mS/cm with ±1.5% full scale accuracy. This range is suitable for measuring higher-conductivity solutions, such as some industrial water samples or concentrated salt solutions. Other models, like the ST10C-B and ST20C-B, measure up to 1,999 µS/cm, which is equivalent to 1.999 mS/cm. For applications requiring measurement above 19.99 mS/cm, alternative instruments may be necessary. The selection of the appropriate model depends on the expected conductivity range of the samples. All models require separate electrodes, which must be compatible with the intended measurement range.
