De ADT835 is een draagbaar kalibratiebad met een compact bad formaat van 90 x 90 mm, waarmee een nieuwe standaard wordt gezet voor krachtige, ruimtebesparende kalibratieoplossingen. In tegenstelling tot typische gecombineerde droog / vloeistofbaden is de ADT835 uitzonderlijk veelzijdig en geschikt voor temperatuursensoren van vrijwel elk type, formaat of vorm. Het innovatieve ontwerp ondersteunt zowel batch- als veldkalibraties met gemak, met behoud van uitstekende stabiliteit, uniformiteit en nauwkeurigheid. De ADT835 combineert de precisie en betrouwbaarheid van een traditioneel kalibratiebad met de draagbaarheid van een droge bron en is een betrouwbare keuze voor veeleisende kalibratieomgevingen.

De ADT835 levert uitzonderlijke prestaties door een slim, gebruikersgericht ontwerp. De geavanceerde datalogging mogelijkheden vereenvoudigen documentatie en helpen fouten of gemiste metingen te minimaliseren. Ingebouwde applicatiehulpmiddelen verbeteren de efficiëntie van de workflow, terwijl de intelligente afstandsbedieningsfunctionaliteit multitasking en een hogere productiviteit mogelijk maakt. Het 6,5 inch TFT touchscreen biedt een intuïtieve interface, waardoor de bediening eenvoudig is, zelfs voor beginnende gebruikers.

[1] The following temperature specifications are all based on the following conditions:

When the environmental temperature is between 13°C~33°C and the calibration bath is within one year after calibration, the confidence level is 95% (K=2), the bath is not open, the working area is theφ75mm circular zone of the bath center, and it is 15mm above the bath bottom and 65mm below the fluid level. The depth of the fluid should be more than 130mm.

When the environmental temperature exceeds the range of 13°C~33°C, the stability and uniformity specification will be 1.25 times larger.

When the bath is open, the stability and uniformity specification will be 1.25 times larger.

[2] The lower limit of controlling range can vary depending on the environmental temperature.

[3] The internal reference accuracy has taken into account the followingl sources of error including calibration uncertainty, stability, uniformity and repeatability.

[4] The external reference accuracy is available for ADT835PC-150 and ADT835PC-250, the reference probe used is Accumac model AM1730-12-ADT.

[5] Stabilty is defined as half of the difference between the maximum and minimum temperature variations of the heat transfer fluid within the working zone over a 10-minute period after the product has reached full stabilization.

[6] Uniformity is defined as half of the difference between the highest temperature point and the lowest temperature point in the valid working area.

[7] Repeatability mainly considers the hysteresis and short-term stability of the reference sensor.

[8] Heating and cooling times are measured from the start of temperature control to when the setpoint is reached within the internal accuracy error band. Actual times may vary depending on ambient temperature, AC power supply voltage, sensor load, and whether the bath is covered during operation.

[9] The typical time to stability refers to the time taken for the temperature in the bath to reach the stability tolerance after the heating or cooling time ends.
