If you are looking for the best dry block oven on the market, look no further! Additel's commitment to continuous improvement, quality and time-saving features are fully represented in the Additel 878 series of reference Calibration Ovens. With three models to choose from, from -40 to 700°C, you will find the perfect fit for your calibration needs.

The Process Calibrator option adds an external reference input, a dual-channel readout for UUTs and a full complement of capabilities to help with everything from measuring temperature sensors, to calibrating thermocouples, self-calibrating the Reference Source and configuring HART transmitters. Each unit comes standard with a large touchscreen display, dual-zone control and Additel's commitment to the best customer service in the industry. We are sure you will be blown away by the outstanding performance... of this game-changing Reference Dry Wells

Process calibrator option
Each model is available with a process calibrator (PC) option. This process calibrator option combines the many features found in a HART documentation process calibrator combined with a dry block calibrator. This option includes the ability to connect a reference PRT and simultaneously measure two devices to be calibrated, mA, voltage, switch, RTD or thermocouple. Besides these measurement functions, this calibrator has the ability to fully document everything , save ‘As found’ and ‘As left’ results, and HART communication. The snapshot function allows you to capture everything and information displayed on the screen at the touch of a button. This device also allows logging data from all channels. There is an automatic step function and a ramp function. By using the reference PRT, you can select to set the dry block oven using the internal sensor or the external reference PRT.
