 Rapid heating and cooling throughout the entire temperature range!
RW-G series has a powerful circulation pump for external and internal circulating. Maintain and control accurate low temperatures as low as -35°C. May be used with refractometers and viscometers.
RW-0525G (5.0L)– Cat.No. JTH-AAH57003U
RW-1025G (10.0L)– Cat.No. JTH-AAH57013U
RW-2025G (20.0L)– Cat.No. JTH-AAH57021K
RW-3025G (30.0L)– Cat.No. JTH-AAH57031K
Operating Features:
- -25°C to 150℃ for RW-25G/
-35°C to 150°C for RW-40G
- Uniformity ±0.1°C at -10°C (based on various conditions)
- Microprocessor PID control/ Auto-tuning/ Calibration
- Digital timer: 1 min to 99 hr 59 min, delayed ON/ OFF
- Over-temperature limiter and low fluid level protection
- 3 different temperature values memorable without auto-tuning
- Digital LED display (0.1°C resolution) with splash-proof keypads
- RS-232 interface available
Constructional Features:
- Turbulence reduced five-speed duplex pump and built-in cooling coil let you use in open or closed bath applications (1 to 3 steps of pump for internal circulation / 4 and 5 steps for external circulation)
- Baffle plate screens circulating pump, heater and sensor to minimize shaking bath fluids and protect sample and
operators from direct contact
- Dry-running protection; automated heating element cut-off and audible and visual warning
- Seamless stainless steel tank with a reservoir drain that resists corrosion and make cleaning easy
- Use CFC-free refrigerant R-134A, R-404A and double service valve to prevent the leakage of refrigerant
- Quick-release front grille for easy condenser cleaning and space saving design uses minimal bench space
