The DIGIVAC 801W is a drop in replacement for the Varian 801 and other Hastings and Fredericks gauge controllers which mount in the industry standard 3 bolt pattern.

The DIGIVAC Model 801 is our best selling panel mount gauge, and the industry's best value for a rugged vacuum gauge for measuring through 6 decades of wide range rough vacuum with SPDT controls. This unit measures vacuum in Torr and uses the rugged Varian 531 thermocouple vacuum gauge tube. The gauge controller is easily mounted with mounting screws in a 1.58" bolt radius with all wiring easily accessible. The DIGIVAC has no moving parts so is highly resistant to shock, therefore requires infrequent calibration. The DIGIVAC gauge controller has a large bright LED display which can be easily read from across the room, or in dimly lit locations.

This gauge measures from 1 micron (1x10^-3 Torr) all the way up to 760,000 Microns (760 Torr) or Atmosphere. The wide range of this vacuum instrument enables users to easily troubleshoot their system. This gauge can also output vacuum readings to an optional RS232 serial connection. This output can be used to graph and plot historical data with the Digivac plotting software, and can also be used as a vacuum transmitter to a PLC or other device.

This unit has the varian 801 standard 3 hole mounting pattern or an optional 4 hole hastings pattern and is microprocessor based. Installation is easy.. simply remove the analog gauge and mount the Digivac 801W faceplate to the outside of the panel. The display and electronics mount behind the panel with the screws provided. The display is visible through the clearance hole normally provided for the meter body.

Vacuum instrumentation with everything you need to go to work

Each DIGIVAC Vacuum Instrument comes with:

A vacuum gauge controller
A thermocouple vacuum gauge tube (vacuum sensor)
A cable to connect the vacuum gauge controller to the thermocouple vacuum gauge tube
An AC adapter that runs on 100-240VAC, 50/60 Hertz
Pre-tested under actual vacuum against a NIST standard

Optional Features and Prices

Description Options Qty Price

Model 801W $425.00

2C The units listed with Control have the ability to turn on an external device via two SPDT external connections allowing controls to be activated at two vacuum set-points. The relays activate at and remain on below the set-points $75.00

5v5T A voltage output available on the 200 or 801W that goes from 0 to 5 volts at 1mv per mTorr, where 1 micron is 1 mv, and 5 Torr is 5 Volts $75.00

Cal Calibration of a Digivac Vacuum gauge against a NIST traceable standard - included on all new gauges $0.00

DS Digivac software which collects and graphs vacuum data on a PC through RS232 or ethernet communications - requires RS232 or Eth option $300.00

Hast Hastings 4 hole mounting pattern to replace hastings gauges like the vt-6 $0.00

LBD A Linear by Decade scheme where the leading digit is scale, and the last digit is the vacuum reading. For example: 0.995 Volts = 0.995 Torr, 1.010V = 10.1T, 2.1V =100T, and 3.760V = 760T $75.00

mBar Displays vacuum reading in mBar $0.00

NISTCal Calibration of a Digivac Vacuum gauge against a NIST traceable standard with data $190.00

RS232 Enables vacuum measurement to be transmitted to a PC or another RS232 device through a DB9 female interface. Includes 6 foot DB9 male to female serial cable $75.00
