Additel ADT875-1210 Dry Well Calibrator

Fits benchtop thermocouple / dry-well calibration where you need controlled heat from 100 °C to 1210 °C with ±0.1 °C stability.

Key advantages

100…1210 °C control — ultra-high-temperature dry-well / TC furnace class.
±0.1 °C stability — display accuracy ±1.2 °C @ 100/300/600 °C; ±1.6 °C @ 900 °C; ±2.0 °C @ 1210 °C.
6.5 in color touch UI — 0.01 °C resolution; USB/RJ45/Wi-Fi/Bluetooth.
ISO 17025 data included — accredited calibration with data as published for the unit.

Typical applications

Lab calibration of thermocouples and high-temperature sensors.
Metrology benches needing a portable furnace form (10.6 kg class).
Work cells that optionally add PC electronics (TC/mA/V/HART/switch).

Selection guide

Output / options — Heat source; optional PC electronics: TC channels, mA/V measure, 24 V, HART, switch test.
Supply — 90–254 VAC, 45–65 Hz, 580 W.
Inserts — Metallic interchangeable inserts, OD 24.8 mm; XR/XS insert styles.
Ambient for guaranteed accuracy — 8…38 °C (datasheet).
Display — 6.5 in (165 mm) color touch screen; resolution 0.01 °C.
Communication — USB A/B, RJ45, Wi-Fi, Bluetooth.

Common mistakes

Ordering ADT875 when the uncertainty budget needs the higher-accuracy ADT878 sibling.
Ignoring guaranteed-accuracy ambient band 8…38 °C for lab placement.
Specifying insert bore pattern without confirming XR vs XS style and 24.8 mm OD.
Assuming PC electronics (TC/mA/V/HART/switch) are base — they are optional.
Underestimating heat-up (~50 min 23→1210 °C) and 15 min typical stability time in the work plan.

When to RFQ / what to tell us

Setpoint band inside 100–1210 °C and whether ADT875 accuracy is enough vs ADT878.
Insert style (XR/XS) and bore layout; quantity of spare inserts.
Optional PC electronics (TC channels, mA/V, 24 V, HART, switch test).
Supply region (90–254 VAC) and whether ISO 17025 cert with data must ship with the unit.
Quantity, ship-to country. Compatible with Additel ADT875-1210 workflows — we do not claim authorized-dealer status.
