Product overview: NtS-40460DV hand-held vacuum gauge is a newly developed vacuum degree tester for low-temperature pressure vessel according to TSG r7001-2004 "regular inspection rules for pressure vessel", gb18442-2001 "low-temperature adiabatic pressure vessel", GB/ t1843-2001 "test method for low-temperature adiabatic pressure vessel" and other national standards. The instrument is suitable not only for domestic thermocouple vacuum regulator of different types, but also for Teledyne hastingDV4 and dv-6 thermal ti vacuum regulator. It is a portable vacuum measuring instrument compatible with the international and domestic mainstream thermocouple vacuum regulation, with high cost performance. The product has been applied for the national patent. It has the obvious advantages of quick measurement sound, good repeatability and stability, wide measurement range, easy operation and so on. It is an ideal vacuum measuring instrument for low-temperature adiabatic pressure vessel at present. The instrument can also be used for vacuum measurement in metallurgy, chemical industry, machinery, electronics, medicine, refrigeration and other industries. Functional features: Four in one, low temperature adiabatic pressure vessel professional vacuum tester; Compatible with vacuum regulation of ZJ-51, ZJ-54D, DV4 and DV6; The use of large-scale high-performance professional data processing chip, more accurate measurement; Large font with backlight 4 bit LCD digital display; All Settings and transitions are made using light touch electronic switches; With the function of setting memory, you can avoid the trouble of resetting on the power; Electronic current automatic regulation, stable and reliable: The measurement unit can be arbitrary conversion between Pa and Torr Low voltage automatic detection and reminder and intelligent charging management system, safe and assured Large capacity lithium battery power supply, longer service time The appearance is beautiful, easy to operate, easy to carry Main technical parameters: Regulatory model:ZJ-51/007B; ZJ-54D/ZJ-53;DV-4;DV-6 Measurement range :(0.1-300)Pa; (0.1-2000)Pa; (1.3-3000)Pa/(1.3-5000)Pa; (0.13-180)Pa Current setting :(80-160)mA; (20-30)mA; Adaptive;Adaptive Measurement error: no more than 30%(within the effective range) Display resolution: 0.001Pa Measurement unit :Pa/ Torr Operating current :(30-170)mA Power supply :37V 1800mAh high-capacity lithium battery, which can work for 6-12 hours Net weight: no more than 65g Environment: temperature: (0-45) ℃: relative humidity: < 90%
