Pressure, temperature and refrigerant calculations

View saturated temperature, superheat and subcool in real time.

The PTC900 combines compound pressure measurement with a refrigerant library of more than 160 refrigerants, allowing technicians to view saturated temperature, superheat and subcool calculations directly on the gauge.

  • Compound pressure measurements for AC/R service work.
  • Refrigerant library with over 160 refrigerant types.
  • Real-time saturated temperature, superheat and subcool calculations.
  • Pressure accuracy of ≤0.06% of full scale.
  • Bluetooth® remote viewing, logging, exports and alarms through the Appion Central™ app.

Appion Central™ app

Remote monitoring for pressure and temperature diagnostics.

Pair the PTC900 with the Appion Central™ app for remote real-time readings, live data logging, multiple simultaneous gauge readings, exportable results and custom alarm notifications.

This helps technicians monitor complex, high-efficiency systems while keeping refrigerant loss low by taking readings directly from system access ports instead of through long hoses and manifolds.

Flexible temperature clamp

Fast response temperature sensing on standard and larger pipes.

The included temperature clamp fits pipes from 1/8 in. to 1 5/8 in. diameter. The clamp’s temperature sensor can also be removed and zip tied to larger pipes, while its low thermal mass and isolated contact sensor help improve response time.

The clamp has IP67 water resistance, a 6 ft / 1.82 m cable and an 8 second sensor saturation time under typical conditions.
