Resistance Vacuum Gauge
ZJ-52 series resistance vacuum gauge is now a widely used low vacuum measuring gauge.
ZJ-52 series resistance vacuum gauge is now a widely used low vacuum measuring gauge. After special processing, its heating filament has the advantages of wide pressure measuring range, stable performance, good consistency, quick response time and long life. Its cover employs DM-305 glass, aluminum alloy, stainless steel and porcelain for sealing.
Major Technical Specifications:
1. Measuring Range: 1x105 to 1x10-1 Pa.
2. Within the range of 1-3000 Pa, relative deviation of the calibration curve and the standard characteristic curve is less than 30%.
3. It can be used for reference measuring within the range of 10-1-1Pa and 3000-105 Pa.
4. Vacuum degree within the gauge is not less than 5x10-2 Pa before unsealing.
Cautions for Operation:
1. Full range and zero point should be calibrated in matching with vacuometer before use.
2. Better be installed vertically.
