Grant LTC4R provides outstanding performance for routine and sophisticated applications requiring accurate temperature control in the range of -30 to 100℃. The LTC4 includes the TX150 heating circulator and an R4 tank/refrigeration unit, complete with insulated tubing and clips to form a system ready to use.

Benefits

• Powerful pump for external circulation, maximum flow 18 L/min, maximum pressure 310 mbar
• Full-colour QVGA TFT display
• Setpoint, plus three adjustable preset temperature values
• Timer function for reaction timing, 99 hours, 59 minutes, with audible alert and heater control
• Liquid selection safety feature adjusts for temperature range or heater power
• Fault indication display
• Programmable relay
• Two-point user recalibration of internal and external probes (TXPEP, TXSEP)
• Off-set adjustment for optimal isothermal performance
• Can be programmed to switch the refrigeration on and off during a heating and cooling program
• Memory capacity for one program of up to 30 segments
• Choice of languages: English, French, German, Spanish and Italian
• Low liquid protection by float switch
• Adjustable over-temperature cut-out
• Convenient accessory clamp available for fitting to vessels
• Stability ± 0.1℃

Note: The refrigeration unit can be switched off independently of the circulator to allow heating only applications. All the refrigeration base units can be used up to a maximum temperature of 100℃.

The TX150 Optima™ is a high-performance programmable digital heating circulator with an exceptionally simple user interface. This allows for fast set-up of multiple parameters through a powerful menu system and provides sophisticated control for temperature-controlled applications.USB connectivity is available to a PC or laptop. It is programmable with Labwise™, a software program to set all parameters, including programs, via the PC. Labwise™ also features real-time status windows, a graphic display of the controller's performance as a program is run, and allows data to be logged for future recall and analysis.

Applications

• University research/teaching – temperature control of external equipment including spectrophotometers & refractometers
• Circulation of temperature control fluid to jacketed vessels, cooling crystallisation vessels
• Industrial laboratories – temperature probe calibration, product testing, product QC, temperature control of external equipment
