Output
Display only (current/average/min/max/differential); no analog transmitter output
Supply
9 V alkaline battery (included, user replaceable)
Ambient temperature
14–140 °F (−10–60 °C)
Display
Dual-line 4-digit LCD with backlight; current and average
Fits multi-parameter environmental surveys where you need a Dwyer EMMA—temperature 14–140 °F (−10–60 °C), RH 0–100%, sound 30–130 dB(A)/35–130 dB(C), illumination to 50,000 lux class, and related environmental functions on a 9 V handheld display-only meter.
