T310 Portable digital pressure gauge


Designed to operate as a pressure gauge and digital milliammeter, giving it greater versatility and allowing the calibration of pressure electronic transmitters with a single instrument. Datalogger function included. Great displayed.

The Tinycal T310 series digital pressure gauges are microprocessor-based portable instruments designed and manufactured by Gometrics to indicate pressure values. The instrument is designed to function as digital manometer and milliammeter, which gives it greater versatility and allows calibration of electronic pressure transmitters with a single instrument, reading both the generated pressure and the 4-20 mA signal from the transmitter output, at the touch of a key.

The pressure sensor is built into the instrument and is made of stainless steel. This, together with its ability to withstand excess pressure, ensures the long life of the instrument.

The keypad on the front has an ergonomic design specially created for one-handed operation, allowing the following functions:

  • Change of engineering units (32)
  • Auto-zero, max./min.
  • Input selection: pressure or current

The compact design of the Tinycal gauge allows for quick and efficient calibration operations in the field and in the shop. It also has a lectern-style desk stand for easy reading.
