About REED INSTRUMENTS

REED Instruments is a manufacturer of portable test and measurement instruments, with a catalog that includes ultrasonic thickness gauges, digital refractometers, gas analyzers, calipers, light meters, and related accessories. The brand is known for producing handheld, battery-operated devices that address common field and bench measurement tasks. Products are typically designed for industrial, environmental, and quality-control applications where a compact, self-contained instrument is required. Many REED instruments are available with or without calibration certificates, and some models include data logging or output capabilities for recording and transferring measurements.

3G Electric supplies REED Instruments products globally, offering individual instruments, kits, and consumables. The line includes ultrasonic thickness gauges such as the TM-8811, which measures material thickness from one side with an accuracy of ±0.5% and a maximum frequency of 5 MHz. Couplant gels, including water-soluble options in 0.25 L applicator bottles, are available for use with these gauges. Digital handheld refractometers, like the R9510, measure Brix in liquids with automatic temperature compensation and an accuracy of ±0.2% Brix. Gas analyzers, such as the R9905, monitor carbon dioxide, temperature, and relative humidity, and feature a triple LCD display with backlight and a sound alert for CO₂ thresholds. Calipers, including the R7406 step-type model, offer a 0 to 6 in (0 to 150 mm) range with 0.0005 in resolution and IP54-rated dust and splash resistance. Data logging light meters, such as the R8100SD-KIT, measure daylight and LED light intensity, store up to 99 records, and provide RS-232 connectivity for data transfer.

These instruments are used in applications such as corrosion monitoring, quality control, HVAC assessment, and environmental testing. The product families cover measurement parameters including thickness, refractive index, gas concentration, dimensional length, and light intensity. Build characteristics vary by model but include IP-rated enclosures for dust and splash resistance, battery power (e.g., 9V for the R9905), and accessories such as carrying cases and probes. 3G Electric supports the REED Instruments line by stocking a range of these products and providing access to related consumables and calibration options. For procurement and engineering teams, the catalog includes both standard and NIST-calibrated versions of certain instruments, allowing selection based on documentation requirements. Technical specifications, including accuracy, resolution, and operating ranges, are available for each product to assist with integration into existing measurement programs.

Frequently asked questions

Common questions about REED INSTRUMENTS from 3G Electric.

What is the measurement accuracy of the REED Instruments TM-8811 ultrasonic thickness gauge?

The REED Instruments TM-8811 ultrasonic thickness gauge has a thickness measurement accuracy of ±0.5%. It operates at a maximum frequency of 5 MHz and is designed to measure material thickness from one side. This makes it suitable for applications such as corrosion monitoring and quality control where access to both sides of the material is limited. The gauge is available as a standard model or with a NIST calibration certificate (TM-8811-NIST), which includes a carrying case, probe, and ultrasonic couplant gel.

What is the accuracy and resolution of the REED Instruments R9510 digital handheld refractometer?

The REED Instruments R9510 digital handheld refractometer measures Brix (sugar content) in liquids with an accuracy of ±0.2% Brix and a resolution of 0.1%. It features automatic temperature compensation, which helps maintain measurement stability when sample temperatures vary. The instrument is battery-operated and designed for handheld use in field or laboratory settings. Typical applications include food and beverage production, agriculture, and industrial process control where Brix measurement is required.

What parameters does the REED Instruments R9905 gas analyzer measure?

The REED Instruments R9905 gas analyzer measures carbon dioxide (CO₂) levels, temperature, and relative humidity. It features a triple LCD display with backlight and a sound alert for CO₂ thresholds. The instrument is battery-powered (9V) and provides PPM accuracy for CO₂ measurements. It is used for indoor air quality assessment in environments such as offices, schools, and industrial facilities. The R9905 is a portable, handheld device suitable for spot checks and continuous monitoring.

What are the specifications of the REED Instruments R7406 caliper?

The REED Instruments R7406 is a step-type caliper with a measurement range of 0 to 6 inches (0 to 150 mm) and a resolution of 0.0005 inches. It has an accuracy of ±0.001 inches over the range. The caliper is IP54 rated for dust and splash resistance, making it suitable for use in machining, quality control, and inspection environments. It does not include SPC output. The R7406 is a digital caliper designed for precise step measurements.

What are the features of the REED Instruments R8100SD-KIT data logging light meter?

The REED Instruments R8100SD-KIT is a data logging light meter that measures and logs light intensity from daylight and LED sources. It features an LCD digital display, RS-232 connectivity for data transfer, and stores up to 99 records. The kit includes the R8100SD meter. It is used for lighting assessment in workplaces, educational facilities, and industrial settings. The meter allows users to record and review light levels over time, supporting compliance with lighting standards and energy audits.

What couplant gels are available for REED Instruments ultrasonic thickness gauges?

REED Instruments offers water-soluble ultrasonic couplant gels in 0.25 L applicator bottles. These gels are compatible with models such as the TM-8811 and R7900 ultrasonic thickness gauges. The couplant gel serves as a coupling medium between the ultrasonic transducer and the test surface, eliminating air gaps to ensure accurate thickness readings. It is available in single bottles or packs. The gel is a consumable item and should be reapplied as needed during measurements.
