Model 725

Datalogging Humidity/Temp Meter w/ Dual Input

Model 720

Humidity/Temp Meter w/ Dual Input

State of the art dual function meters with two environmental sensors housed in a
remote wand. The sensors can be placed right where they are needed. Both
meters feature triple LCD displays, RH and temperature readings simultaneously,
and a second K-type thermocouple port.

Model 725 has datalogging feature and records up to 16,300 data points. With
an adjustable interval setting, you can record from 4 hours to 678 days worth of
data. Both units feature RS-232 output ports (software optional on Model 720).
Either download data for analysis or control the meter in real-time from your PC.
With the optional TestLink software and RS-232 cable (AK-720), even Model
720 becomes a real-time datalogging meter when attached to a PC.

These meters are ideal for environmental testing, lab monitoring, process control
and building maintenance.

Additional features include:

■ Tripod Mounting Lug

■ Auto Power Off

■ Real Time Clock (Model 725)

■ ∆ Relative Function

(Model 720)

■ Min/Max function
