6332A / 7342A Temperature Calibration Baths

Overview

External footprint and mass: Height: 1080 mm (42.5 in), Width: 445 mm (17.5 in), Depth: 495 mm (19.5 in). Weight: 6332A: 26 kg (57.3 lb); 7342A: 50 kg (110.2 lb). Internal tank and fluid capacity: Inner Tank Diameter: 145 mm (5.7 in); Maximum Fluid Depth: 450 mm (17.7 in); Fluid Volume: 12 liters (3.2 gallons). Thermal performance and measurement characteristics: Operating range (at 23 °C ambient temperature) — 6332A: 50 °C to 300 °C; 7342A: –40 °C to 150 °C. Temperature stability: 0.01 °C (both models). Temperature uniformity (working area) — 6332A: 0.015 °C from 50 °C to 200 °C and 0.02 °C from 201 °C to 300 °C; 7342A: 0.01 °C (full range). Stabilization Time: 20 minutes. Maximum Display Error: 6332A: 1.0 °C; 7342A: 1.0 °C. Heating and cooling performance (manufacturer test conditions with specified heat-transfer fluids): - 6332A: Heating 25 °C to 300 °C (silicone oil, 710): 165 min; Cooling 300 °C to 80 °C (silicone oil, 710): 825 min. - 7342A: Heating –40 °C to 25 °C (ethanol): 35 min; Heating 25 °C to 150 °C (silicone oil, 200.50): 75 min; Cooling 150 °C to 25 °C (silicone oil, 200.50): 110 min; Cooling 25 °C to –40 °C (ethanol): 135 min. Calibration traceability: Factory calibration provided as a limited range calibration traceable to the SI through a national metrology institute. Primary use is as laboratory-grade liquid temperature calibration baths for calibrating and verifying temperature sensors and reference thermometers under industrial manufacturing and calibration-lab conditions. The 6332A covers high-temperature work up to 300 °C for high-temperature probes and process sensors; the 7342A covers a broad interval from –40 °C to 150 °C for low-temperature and ambient-range devices. Selection and workflow considerations: tank diameter (145 mm) and 450 mm maximum fluid depth with 12 liters of fluid determine the largest probe fixtures and assemblies that can be immersed; stabilization Time of 20 minutes and the listed heating/cooling times define realistic cycle times and throughput for batch calibrations. Choice of heat-transfer fluid (silicone oil grades and ethanol as shown) must match the target temperature range and compatibility requirements. Weight and bench footprint favor fixed bench or cart mounting in calibration rooms or production test areas. Factory calibration traceable to the SI supports use as a reference instrument in accredited calibration labs and manufacturing quality-control workflows.
