For your safety
Media & Overpressure:
Warning
(-100kPa 400kPa): Non-corrosive and unpolluted gas;
(Higher than 400kPa): media compatible with 316 Stainless Steel.
Overpressure: 120%.
Burst pressure: 300%
Follow all equipment safety procedures
Do not operate the calibrator around explosive gas, vapor, or dust.
Do not put the battery in the fire or make electricity short circle; Use charger supplied by only.
Never apply more than 32V between mA terminal and common terminal.
Recharge or replace the battery as soon as the battery indicator appears.
Do not allow water inside the case, please clean and maintain the calibrator periodically.
Do not apply more than 11V voltage to rechargeable jack ny problem caused by this is not covered under warranty
To avoid over pressure damages, do not apply pressure that exceeds the limits listed in the pressure specification
To avoid mechanically damaging the calibrator, do not apply torque between the pressure fitting and the calibrator
Do not disassemble the calibrator. Any problem caused by this is not covered under warranty.

Description
The ADT672 is a portable digital pressure calibrator designed to be a rugged calibration tools which has the functions to
calibrate and maintain pressure instruments.
Features:
High-accuracy pressure measure &wide-range temperature compensation Measure function to mA, V and switch
③ HART communication DC24V output
⑤ RS232 port to connect with computer Data logging
⑦ Assistant measure function for time and temperature ⑧ A/C or D/C (rechargeable battery)
According to about functions, ADT672 also have some other common functions as below:
Record the peak pressure Indicate % pressure
③ Pressure leak test Trigger switch control
⑤ Data logging Communicate with HART pressure transmitter
As a master gauge(or reference gauge), ADT672 digital pressure calibrator is to measure or calibrate pressure instruments
such as pressure transmitters, differential pressure sensors, pressure switches, precision pressure gauges, industry pressure
gauges, sphygmomanometers, pressure transducer and others.
