The Klein Tools DTL302 is a dual-input digital temperature logger designed for monitoring, logging, and uploading temperature data. It accepts two thermocouple inputs and connects to a computer via USB for data transfer using included software. MIN, MAX, average, and hold functions enable efficient temperature analysis. A magnetic hanger strap provides hands-free operation. Powered by 2 x AAA batteries or USB adapter. This product has been discontinued. Backed by Klein Tools' 1-year limited warranty.
Is the DTL302 still available?
No — the DTL302 has been discontinued. There is no direct current equivalent in Klein's active lineup.
What did the DTL302 do?
The DTL302 was a dual-input temperature data logger that accepted two thermocouple probes simultaneously, allowing differential temperature logging (e.g., supply and return air on an HVAC system) and timed data recording over an extended session.
What current product comes closest?
For single-point temperature measurement alongside electrical readings, the MM420 or MM720 both include thermocouple input. For multi-channel data logging, a dedicated third-party temperature logger is the current alternative.
