K26500 Thermometer Calibration Bath


Features and Benefits
• Calibrates thermometers, temperature controllers and other temperature instruments against a factory certified thermometer traceable to NIST standards

• Verifies accuracy of routine thermometers

• For temperatures between ambient to 200C (–30C with the use of circulated refrigerated coolant)

• Digital temperature control with temperature uniformity of 0.02C

• Built-in ice bath for performing ice point calibrations

• Meets the requirements of NBS Monograph 150



K26500 Thermometer Calibration Bath
Constant temperature calibration bath for liquid-in-glass thermometers, dial thermometers, digital thermometers and other temperature measuring instruments. Consists of an oil bath with digital electronic control providing temperature uniformity of 0.02C in the range –30C to +200C. Accessory Standard Thermometer is calibrated and certified traceable to NIST standards. Turntable rack inserts in bath to immerse six thermometers or temperature probes and the standard thermometer. Bath depth of 12" (30.5cm) accommodates all partial immersion thermometers and most 15" total immersion thermometers.

Features digital setpoint and display (C/F switchable) of bath temperature for maximum convenience, and over-temperature control to prevent accidental overheating. Built-in cooling coil permits circulation of tap water or refrigerated coolant to permit operation at sub-ambient temperatures or to facilitate rapid cool down for multi-point calibrations. Equipped with drains for oil bath and ice bath.

Temperature Range: –30C to +200C
For sub-ambient temperatures, refrigerated recirculating coolant is required from an external source.
