Calibration and regulation of temperatures from -25 to 200°C with LAUDA calibration thermostats The  (more)ECO calibration thermostat is designed for the specific needs of laboratories that carry out calibration and regulation work on a daily basis. The equipment was specially developed for the precise calibration of thermometers, such as industrial platinum resistance thermometers, temperature probes, thermocouples or electrical thermometers. Liquid calibration baths are considered the most stable temperature source and offer the greatest consistency for comparative calibration of temperature probes and sensors in a laboratory. LAUDA calibration thermostats are specially equipped for the calibration of glass thermometers or electric thermometers; they are an ideal solution compared to heat cabinets and metal block thermostats, as these thermostats transfer heat into the thermoregulation liquid 40 to 60 times better than through the air. The LAUDA ECO REJ 1225 G calibration thermostat is ideal for calibrating glass thermometers or electric thermometers. DISPLAY AND CONTROL The thermostat can be easily and flexibly integrated into your existing work processes thanks to a variety of interfaces, including Profibus, Ethernet or Pt100/LiBus. The large color TFT display offers a clear overview at a glance and allows you to program a variety of temperature curves, which are automatically processed by the thermostat to support your daily laboratory work. - Color TFT display for simultaneous indication of actual and set values ​​and temperature profile graph - Intuitive menu navigation in simple language - Simple entry via cursor and function keys. Additional Tmax button for overtemperature protection - Fully electronic stepless controller with PID action - USB interface as standard - Upgradeable with Pt 100/LiBus module for external control and remote control via command console - Programmer with 150 temperature/time segments separable into 5 programs CONSTRUCTION AND BATH - Thermostatic calibration bath with the latest microprocessor technology and integrated cooling system - Safety class III for operation with flammable and non-flammable liquids. - Too high temperature protection adjustable via menu - Pump with six adjustable power levels - Easy flow control between internal and external circulation - 2 separate chamber design for a constant level in the thermostating chamber - Vertical adjustment for calibration chamber overflow - Stainless steel bath with drain valve Why LAUDA thermostats? Calibration applications require thermostats that maintain a constant, temperature-independent liquid level. To achieve this, LAUDA uses a two-chamber tank, the temperature chamber and the operation chamber, also known as the usable space or buffer chamber. A unit pumps fluid from the heat chamber to the application chamber where, if it is overfilled, it has the potential to overflow back into the heat chamber. The cylindrical working chamber is height adjustable, which makes it possible to adjust the immersion height. The thermometers, completely immersed, can therefore be read directly at the point of immersion. Furthermore, the separate calibration chamber ensures constant immersion depth, regardless of liquid volume expansion, excellent temperature stability of ±0.02 K and homogeneous temperature distribution. Standard accessories - 2 screw caps, 2 closing caps - 1 bath cover Performance graph of the pressure pump on the six levels. GREEN TECHNOLOGY The LAUDA ECO calibration thermostat uses refrigerants compliant with the European regulation on fluorinated gases. Furthermore, the REJ 1225 G is optionally available with natural refrigerants.
