K-type digital thermometer · single & dual input

The DT1311 and DT1312 read temperature with standard K-type thermocouples from −200 to 1,370 °C and show it on a large 4-digit LCD at 0.1 °C resolution. DT1311 is the single-input version; DT1312 adds a second input and displays the difference T1 − T2 directly, which is what you want for differential measurements on heat exchangers, ducts and process lines.

Why it stands out

K-type range from −200 to 1,370 °COne instrument covers −328 to 2,498 °F and 73 to 1,643 K, with 0.1 °C resolution and a large 4-digit LCD.
Single or dual input, one platformDT1311 takes one K-type probe; DT1312 takes two and adds a live T1 − T2 differential reading on screen.
±(1 % of reading + 1 °C)Specified across the full range, with a stated temperature coefficient of 0.02 % of reading + 0.05 °C per °C outside 22 – 28 °C.
Protected probe input, standard connectorThe mini K-type socket accepts third-party probes and is rated for 60 V DC / 24 V AC input protection.
Built to be carriedShockproof protective sleeve, fold-out stand, HOLD and MAX / MIN keys, 10-minute auto power-off and 4 × AAA cells.

FAQ

Which model do I need?

DT1311 is the single-input version — one probe, one reading. Choose DT1312 when you need two points at once, for example inlet and outlet of a heat exchanger, or when you want the difference T1 − T2 displayed directly.

Can I use my own thermocouples?

Yes. Both models use the standard miniature K-type connector, so any K-type probe with the same plug will work. The meter reads the K-type characteristic — the usable temperature range is then limited by the probe you attach.

What is the difference between the meter range and the probe range?

The meter is specified to 1,370 °C, but a standard TP-01 wire probe is rated well below that. For high-temperature work choose a probe rated for the process — the reading is only as good as the sensor.

Are batteries and probes included?

Probes are included: one K-type probe with DT1311, two with DT1312. Batteries are not included — the meter takes four AAA cells.

Why is the reading slow to settle?

Thermocouples respond as fast as their mass allows; thin wire probes settle in seconds, sheathed or surface probes take longer. Keep the probe in contact until the value stabilises.

How do I turn off the auto power-off?

Hold the HOLD key while switching on to cancel it; the auto power-off symbol disappears from the display. The instrument then stays on until you switch it off.
