High-temperature calibration bath 820

for temperature sensorsfor thermometershigh-precision

Presentation
The 820 calibration bath offers a large working volume of 185 × 140 mm with a depth of 300 mm (15 litres). It enables simultaneous verification of multiple sensors, either immersed directly or used with appropriate accessories. The 820 can also maintain reference resistors at a constant temperature.

Operation
The bath fluid is heated to the setpoint and agitated by a propeller mixing system to ensure thermal exchange.

Key features

• Large calibration volume to accommodate numerous sensors
• Wide temperature range: 30°C to 200°C
• Calibration comparison precision: 0.1°C (listed)
• Calibration comparison precision: ±0.01°C (tabulated)

Standard delivery

• Cal Notepad software
• Serial communication cable
• User manual

Notes
Specify the required supply voltage when ordering.
