Overview: The BK40 M Cryostatic Bath is a precision instrument designed for the calibration of
temperature sensors, transducers, and thermostats in both laboratory and field settings. It supports both positive and negative temperature ramps, making it versatile for various calibration needs.
Technical Specifications: The bath features a 10-liter stainless steel tank with a height of 340 mm and a diameter of 85 mm. It includes a stainless steel mixer, safety thermostat, drain cock, and overflow drain pipe. The device is powered by a 230 V - 50 Hz supply and has an electric power rating of 2500 W. It weighs 70 kg and measures 450 x 1270 x 450 mm.
Control and Interface: Equipped with a PID microprocessor controller, the BK40 M offers a resolution of up to 0.01 °C and supports temperature settings in °C, °F, and K. It includes an RS232 serial interface for PC connectivity, allowing for automatic calibration and testing via the AQ2sp software.
Calibration Capabilities: The bath can perform manual or automatic calibration of multiple probes, cyclic life tests, and automatic threshold thermostat tests. It supports data storage and printing, ensuring compliance with ISO 9000 standards.
Fluid Level Adapter: An optional fluid level adapter is available for calibrating glass thermometers. It maintains a stable bath fluid surface and protects against ambient temperature effects.
Performance: The operating range is -40 to +125 °C with a stability of ±0.05 °C. The display resolution is 0.01 °C, and accuracy is ±0.2 °C at 120 °C. Heating and cooling times are 2 °C/min and 0.5 °C/min, respectively.
Accessories: Optional accessories include a multichannel data acquisition unit, custom-made equalization blocks, and various fluid tanks (glycol and silicone oils).
Ordering Information: The BK40 M is available in standard and customized versions, with options for additional inputs and fluid level adapters.
