Low-Temperature Calibration Bath
The GL-1040S is a low-temperature calibration bath designed for metrology and verification in temperature laboratories using alcohol as the working medium. It features an aperture diameter of 138 mm (5.43 inches) and a bath depth of 510 mm (20.1 inches), making it particularly suitable for testing and calibrating long-stem thermometers in laboratory environments. Across the entire temperature range of -42°C to 50°C (-43.6°F to 122°F), the bath achieves a temperature stability of ±0.003°C, providing reliable conditions for high-precision temperature calibration. Equipped with a rapid cooling system, it delivers excellent performance in both efficiency and accuracy. The incorporation of MPtest's jet-stream agitation technology ensures low vibration and quiet operation, contributing to a quiet laboratory environment.
