TPG 201 | Pirani Handheld Vacuum Gauge | NIST Certified

Pre-owned Pfeiffer TPG 201 Portable Pirani Gauge, KF16 inlet, No Kit, Gauge Only | NIST Certified


Pfeiffer TPG-201 Portable Pirani Gauge AC or DC Power Operation.

The Pfeiffer TPG-201 Portable Pirani gauge is a battery operated handheld gauge. It can be operated with a 9V battery, or alternately with a 12V external power supply. With a Measurement range from 1.2 x 103 to 5 x 10-4mbar and an NW/KF-16 flange it’s perfect for low and medium vacuum applications. The TPG-201 has an integrated data logger and can be connected to a computer and operated using DokuStar software (not provided with gauge). The DokuStar Software is only available with the TPG 201/202 Accessories kit.

Pirani Features

The Pfeiffer Handheld TPG 201 and 202 gauges are battery-operated offering an easy way to display and record pressures. The TPG 201 works on the principle of heat transfer (Pirani). The TPG 202 also has a piezo-resistive pressure transducer for the higher-pressure range, which works irrespective of the type of gas. Depending upon the unit, the handheld gauges cover the pressure range of between 900 Torr and 3.75· 10-4 Torr. Handheld units are equipped with a display which allows the pressure to be read off directly on the unit. The readings can also be read out through the USB interface with the aid of DokuStar software. A handy accessory case is optionally available.
