Low-temperature calibration bath GL-1040S

high-precisionfor thermometers

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. - Operating Temperature: Alcohol: -42 ℃ to 50 ℃ (-43.6°F to 122°F) - Working Area: Diameter 138mm (5.4"), Depth 510mm (20.1") - Wetted Parts: 304 stainless steel - Liquid Volume: Approximately 13 liters (3.43 gal) - Stirring Method: Jet stirring, three-speed adjustable - Temperature Control Method: Fully digital PID control - Display Resolution: 0.001 ℃ - Temperature Stability: ±0.002 ℃ /10min at 0 ℃ (32°F) - ±0.003 ℃ /10min at -40 ℃ (-40°F) - Temperature Uniformity: ±0.003 ℃ at 0 ℃ (32°F) - ±0.01 ℃ at -40 ℃ (-40°F) - Heating Time: 60 minutes from -40°C(-40°F) to 25°C(77°F) - Cooling Time: 180 minutes from 25°C(77°F) to -40°C(-40°F) - Operating Voltage: 110VAC ±10%, 60Hz (Customizable Technical Specifications) - Rated Power: Approximately 1500W - Dimensions: 405mm (15.9") x 350mm (13.8") x 870mm (34.3") - Net Weight: Approximately 42 kg (92.6 lb) Key Features / Technical Specifications: - Model: GL-1040S - Temperature range: -42°C to 50°C (-43.6°F to 122°F) - Temperature stability: ±0.003°C - Temperature uniformity: ±0.003°C at 0°C, ±0.01°C at -40°C - Working medium: Alcohol - Bath aperture: 138 mm diameter - Bath depth: 510 mm - Liquid volume: ~13 liters - Material: 304 stainless steel wetted parts - Stirring: Jet stirring, three-speed adjustable - Control: Fully digital PID - Display resolution: 0.001°C - Heating time: 60 min (-40°C to 25°C) - Cooling time: 180 min (25°C to -40°C) - Voltage: 110VAC ±10%, 60Hz - Power: ~1500W - Dimensions: 405 x 350 x 870 mm - Net weight: ~42 kg
