ZJ-53 and ZJ-54 (M713, M714) series short filament thermal couple gauge have the advantages of rapid response, anti-oxidation and stable performance, etc.
Its cover adopts DM-305 glass, aluminum alloy, stainless steel, porcelain, etc.
Major Technical Specifications:
| Type | ZJ-53 and ZJ-54 (M713, M714) | | Operation Parameters: | | | Heating Current | 27.5+-1.5 mA | | Response Time | < 3s | | Measuring Range | 3*102～1*10-1Pa | | 3～1*10-3mbar | | 2.25～0.75*10-3Torr | | Vacuum degree within the glass gauge（ before unsealing.） | not less than 5*10-2Pa | | not less than 5 mbar | | not less than 3.75 Torr | | Within the range of which relative deviation?? between the calibration curve and the standard characteristic curve is less than +-15%. | 1～50Pa | | 1*10-2～5*10-1mbar | | 0.75*10-2～3.75*10-1Torr | | Vacuum degree within the glass gauge（ before unsealing.） | not less than 5*10-2Pa | | not less than 5 mbar | | not less than 3.75 Torr | Cautions for Operation:
1. Measuring heating current value before unsealing.
2. The labeled heating current of the metal gauge can be referenced for operation.
3. Better use the gauge under vertical installation.
