technical parameters: 1
Main technical indicators Product Name: Refrigeration constant temperature lees model: gjm-300 temperature range: - 30 ~ 95 ℃ temperature fluctuation: & plusmn; 0
01 ℃ / 10min temperature uniformity: horizontal temperature field ≤ 0
01 ℃, vertical temperature field ≤ 0
02 ℃ working area size (mm): Ф 130× Depth 480 overall dimension (mm): length 750 & times; 550 & times wide; High 1100 (high worktop) tank volume: 18 L liquid medium: (1) when the working temperature is - 30 ℃ ~ 5 ℃, absolute ethanol is generally used as the liquid medium; (2) when the working temperature is 5 ℃ ~ 95 ℃, the liquid medium is generally soft water
Operating ambient temperature: * * 30 ℃ total power: 2kW power supply: AC220V / 50Hz net weight: 120kg 2
Structure and materials: thermostatic bath, control system, refrigeration system and mixing system adopt integrated structure
The inner tank of thermostatic bath and the shell of the whole machine adopt hairline stainless steel plate thermal insulation material: the base of foaming agent box is equipped with universal wheel, The two overflow water tanks with brakes in the direction of the control panel adopt external plastic water tanks (1) control system: control instrument: domestic * * temperature controller, temperature sensor: PT100 platinum resistance (special) heating control output adopts bidirectional thyristor (2) refrigeration system: compressor: totally enclosed compressor
Refrigerant: R404 environment-friendly refrigerant (transparent, tasteless, non-toxic, non combustible, explosive and chemically stable refrigerant) cooling system cooling mode: air cooling; Low temperature pipeline: the low temperature pipeline adopts oxygen free copper pipe, nitrogen filled welding and special pipe routing process (the traditional method adopts ordinary copper pipe, and the direct welding method is easy to produce oxide on the inner wall of the copper pipe, resulting in blockage of the refrigeration system, so that the test does not cool down or slow down) to ensure the welding quality
Refrigeration time: the standard time range is 100 minutes
This product takes about 60 minutes from room temperature to - 30 degrees
The mixing system is composed of motor lengthened stainless steel mixing blades
