(930g), Model 720: 1.8 lbs. (820g) Model 725 Datalogging Humidity/T emp Meter w/ Dual Input Model 720 Humidity/T emp 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 T estLink 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 725 720 Easy to read - Triple Display Tripod Mountable (tripod not included) SUPPLIED: Model 725 : Datalogging meter, Instruction manual, Battery, Carry case, PC Software, RS-232 Cable, and K-type Bead Probe Model 720 : Meter, Instruction manual, Battery, Padded pouch, and K-type Bead Probe OPTIONAL: BE-9 AC Adapter, AK-720 T estLink Software w/RS232 Cable (Model 720) See page 87 for K-type Thermocouple Probes Specifications models Accessories 720 & 725 One Year Warranty
