pH Meters & Refractometers

This data logging Indoor Air Quality (IAQ) Meter has the ability to record samples on internal memory and keep track of registered readings with a time and date stamp. The R9905 features a Nondispersive Infrared (NDIR) CO2 sensor for stable, accurate readings and the option to track live measurements via software. Application: Environmental Monitoring in buildings, schools, hospitals and factories Verify HVAC/R system installation and system performance Manufacturing processes where high CO2 concentrations must be measured, such as fire extinguishers, wine, soda and sugar industries ...

Dual function tachometer features the ability to measure RPM with non-contact (visible light) and contact (ft/min / m/min) measurements quickly and accurately. This tachometer features both the ability to measure RPM (revolutions per minute) in rotational equipment and surface speed m/min (meter per minute) / ft/min (feet per minute) with included contact adapters. The R7140 uses visible light for non-contact measurements to read up to 12" (300mm) from any target. The R7140 features a durable ABS plastic housing to assure years of maintenance free performance. Features: Provides fast and ...
