Testo A\C Refrigeration

Measurements Matter!

Why choose a Testo Digital Gauge? Because the measurement is never compromised!

When it comes to accurately charging, commissioning and testing A/C and Refrigeration systems the Testo Digital Gauges are considered the most accurate instruments on the market. All measurements are not created equal! Utilizing a lower range pressure transducer means that Testo Digital Gauges are more accurate in the designed working range. Because the sensors are ceramic, they can handle over pressurization at almost twice the working pressure. Special designed temperature clamps that use NTC thermistors also mean higher accuracy, repeatability, and a lower over measurement uncertainty than other digital gauges. The Testo Digital Gauges come fully calibrated out of the box unlike manifolds using K-type thermocouples and recalibration is not required when the probes are replaced or even switched in the meter sockets. Because the Testo Digital Gauges are temperature compensated, atmospheric compensated and protected from EMF, you can be assured of accurate quick measurements that are right the first time every time.
