• Pressure Range: 0.01 to 100.00 mTorr, 1 to 2000
mTorr, 0.01 to 20.00 Torr, depending on designed
range of instrument.
• Calibration: Air or Nitrogen.
• Accuracy: Better than 5% of value or:
(for 100 mTorr gauges) ±0.03 mTorr,
(for 2000 mTorr gauges) ±3 mTorr,
(for 20 Torr gauges) ±0.03 Torr,
whichever is larger.
• Set Point Range: Full scale, equal to full scale range
of instrument.
• Set Point Repeatability: 2 digits.
• Analog Output: 0 to 2.000 volts = 0-2000 mTorr into
2000 ohm load or higher; or 2.000 volts = 20.00 Torr;
or 1.0000 volt = 100 mTorr. 2 pin connector included.
• Gauge Tube: Gauge tubes for 2000 mT and 20T
have 1/8 inch NPT male thread or fit into quick
connects sized for 1/8 inch pipe (0.405 inch dia.)
100 mTorr tube has 3/4 inch O.D. smooth tubulation.
• Power Consumption: Approx. 1 Watt for indicator,
2 Watts for Controller @ 115 VAC (4 Watts for 20 Torr
models).
• Relays: SPDT 3 Amp @115VAC; non-inductive loads.
• Temperature Effects: (For 2000 mT): changes in
ambient temperature between 0°C and 50°C
change the reading less than 0.2 mT per °C at 50
mT; less than 4 mT per °C at 900 mT. (For 20 Torr):
Changes in ambient temperature between 0°C and
50 °C change the reading less than 0.01 Torr per °C.
(For 0.01 to 100 mT): Changes in ambient temperature
between 0° C and 50° C change the reading less than
0.004 mTorr per °C at hard vacuum and 0.4 mTorr at
50 mTorr.
• Line Power: 115VAC, 50/60 Hz; 230 VAC optional at
no additional cost.
