Hollow glass dew test instrument
Standard:
GB/ t11944-2012 "hollow glass" about dew point measurement section.
Application:
It is used to detect whether the surface of the hollow glass sample is exposed under standard conditions and methods.
Description:
The imld-b hollow glass dew point instrument is an instrument manufactured according to the technical conditions specified in GB/T 1194-2012
features:
1. Using semiconductor tertiary refrigeration technology, refrigeration temperature can be set and control precision, cooling speed, convenient operation, not only can be used in the test room, and can be tested at the scene, do not need to use volatile dry ice, convenient use and low cost.
2. The probe and refrigeration unit can be completely separated, convenient and practical and not subject to the direction of the test piece.
3. The integration of the power, cooling, cycle and control system, realize the whole process of automatic control, chassis and probes are connected by a hose, when detecting probe face contact with the specimen, probe face to any direction.
4. Pt100 temperature probe is adopted, with high precision and accurate data.
5. Temperature control adopts microcomputer temperature control PID control technology with high temperature control precision and high temperature stability.
Technical parameters:
1. The temperature measuring probe job: - ~ 60 ℃ and 40 ℃
2. Measurement probe diameter: 50mm.
3. Digital display thermometer range: - 65 ℃ to + 50 ℃ (note: measuring range adjustable)
4. The temperature resolution: 1 ℃
5. Specimen size: 510mm * 360mm.
6. Control box size: 470mm * 550mm * 700mm.
7. Test environment: temperature: 23 ℃ + 2 ℃ relative humidity: 30% ~ 75% RH
