OHAUS

OHAUS Corporation, founded in 1907 in the United States, is a manufacturer of precision weighing and measurement instruments for laboratory, industrial, and educational applications. The company's product portfolio includes analytical and precision balances, bench scales, industrial scales, moisture analyzers, pH meters, conductivity meters, dissolved oxygen meters, and related accessories such as dry bath blocks, flask clamps, and shaker harnesses. OHAUS products are used in quality control, research, production, and process monitoring across sectors like pharmaceuticals, food processing, chemical manufacturing, and environmental testing. Key technical attributes of OHAUS equipment include readability ranges from 0.1 g to 0.002 lb, stainless steel weighing surfaces for corrosion resistance, RS-232 and RS-485 connectivity for data integration, and battery-powered options for portable use. Many models are not IP-rated or washdown-rated, indicating suitability for controlled indoor environments rather than wet or harsh industrial conditions. 3G Electric stocks over 1,000 OHAUS SKUs, including balances, scales, meters, and accessories, with datasheets and logistics support for global procurement. The range covers entry-level portable balances like the CX series to industrial bench scales such as the Defender 5000, as well as laboratory peripherals like modular dry bath blocks and tube racks. OHAUS instruments are designed for repeatable accuracy and durability, with materials like anodized aluminum and PVC used in accessories to withstand routine lab use. 3G Electric provides technical specifications and application guidance to help engineers and procurement specialists select the appropriate OHAUS model for their specific weighing or measurement task.

Frequently asked questions

Common questions about OHAUS from 3G Electric.

What types of OHAUS balances and scales are available through 3G Electric?

3G Electric supplies OHAUS industrial balances, bench scales with column-mounted indicators, and portable balances. Examples include the Defender 5000 bench scale with stainless steel surface and RS-485 connectivity, and the CX1201 portable balance powered by AA batteries with 0.1 g readability. These are suitable for general weighing in labs, warehouses, and production floors where washdown or IP-rated protection is not required.

Are OHAUS dry bath blocks compatible with other brands of dry baths?

OHAUS modular dry bath blocks, such as the anodized aluminum block with 12 wells for 15 mL tubes, are designed for use with OHAUS dry bath units. Compatibility with other brands is not specified by the manufacturer. The block includes a thermometer well and is made from anodized aluminum for thermal conductivity. For cross-brand use, verify dimensions and well spacing against your existing equipment.

What connectivity options do OHAUS industrial bench scales offer?

OHAUS industrial bench scales like the Defender 5000 provide RS-485 ports, while models such as the D33P75B1R1 offer RS-232 connectivity. These serial interfaces allow data transfer to printers, computers, or PLCs for recording and process control. The scales are not IP-rated, so they are intended for dry indoor environments. Check the specific model's datasheet for supported protocols.

Can OHAUS dissolved oxygen meters be used for field measurements?

Yes, the OHAUS ST300D-B handheld dissolved oxygen meter is battery-powered (4 AAA batteries) and portable, making it suitable for field use. It measures DO concentration up to 400% with ±1% accuracy and 1% resolution, plus temperature with 0.3°C accuracy. It is designed for water quality testing in environmental monitoring, aquaculture, and wastewater treatment applications.

What materials are OHAUS flask clamps and shaker accessories made from?

OHAUS flask clamps, such as the 1 L capacity model (MPN 30400102), are constructed from PVC with a rubber mat to secure flasks during shaking. Universal harnesses for shakers (MPN 30400123) are made from aluminum with rubber components. These materials provide chemical resistance and durability for routine lab use with vortex mixers and rockers.

Are OHAUS tube racks suitable for staining procedures?

Yes, the OHAUS tube rack (MPN CLN-STNRK) is made from stainless steel and designed for slide staining applications. It holds up to 10 samples and measures 3.5 inches wide by 23.7 inches deep. The stainless steel construction resists corrosion from staining reagents, making it appropriate for histology and cytology labs.
