Provide calibrations from 1-30 inHg vacuum (0.03-1 bar) and 3-500 psi (0.2-35 bar) in one extremely accurate yet easy to use primary standard. A selector valve converts the unit from pressure to vacuum mode without the need to exchange pistons.Manufactured to the highest standards with certified accuracies traceable to International Standards Laboratories.

Is available in a variety of pressure ranges from 0-5 psi to 0-3000 psi, and is an economical alternative to the Model 7250xi and 7250i. It provides 0.003% of full scale precision and can control to the set point in 15 seconds with no overshoot. When a higher level of performance is required, please refer to the 7250i and 7250xi Digital Pressure Controllers.

Calibrates your analog and digital workload accurately and economically. Its high voltage and current compliance makes analog workload calibration easy and precise. And built-in protection circuitry protects it against damaging input voltages.

Finally, a digital substitute for your mercury-in-glass thermometers! Accurate and repeatable to ± 0.05 °C over its full range, the 1551A/1552A “Stik Thermometer is the new “gold standard" of industrial temperature calibration. Whether working outdoors in environments where potentially explosive gases may be present or on the floor of a processing plant, the intrinsically-safe, battery operated, portable reference thermometer is designed to go where you work
