VacuGuard – The VacuGuard is a small, portable instrument designed for use with Televac 2A thermocouple or competing DV-4 and DV-6 series thermocouple sensors. The VacuGuard is powered by a 1.5 V D cell battery and will accept either single-use or rechargeable batteries. Front-panel controls consist of a toggle power switch and a three-position sensor select switch. The digital display is a four-digit, seven-segment, 0.6” high, red LED protected by a grey neutral density filter making the display easy to read in bright ambient conditions. At 23 ounces, this lightweight instrument has a small size of 4” x 2.5” x 5.5” and can read from 1×10-3 Torr to 20 Torr.

MX2A Active Gauge – The MX2A utilizes an easily replaceable Televac 2A thermocouple vacuum sensor. It has a variety of features including a wide range of measurement from 1 × 10-4 Torr up to 1000 Torr, RS-485 communications, two programmable set points, and a selectable analog output. The bright OLED display makes it easy to read from a distance. Options can be set from four capacitive touch controls located on the top of the unit or through RS-485 communications. The extensive selection of fittings, simplicity of use, ease of sensor replacement, and competitive cost make this unit an excellent choice for a variety of vacuum applications.
