The Watchport/H Humidity & Temperature Sensor is the first Plug-and-Play USB device for monitoring relative humidity (RH) levels and temperature in branch server rooms, kiosks, factories or any mission-critical environment. Watchport Manager software provides centralized device status and historical data logging, and allows the integration of multiple Watchport devices without additional software development. The fully customizable software enables users to receive email, beeper or phone alerts when RH levels and/or temperatures fall outside a specified range, making it an ideal remote monitoring solution. Watchport/H can pre-empt damage to equipment and facilities, as well as reduce costly downtime and maintenance.PRODUCT FEATURES:Includes USB-attached base unit, RJ-45-attached sensing device and Watchport Manager software;Sensor utilizes ASCII command interface to collect both %RH and temperature data;Temperature compensated RH readings;Watchport Manager software sends email, beeper or phone alerts for remote monitoring;Includes 2 m (6.56 ft) cable terminated in RJ-45 connector and 1 m (3.28 ft) USB cable;Extend distance between base and sensing device with CAT 5 UTP cable, or use crimping tools to shorten cable;Measurement range: 0 to 100% RH, noncondensing;Maximum measurement rate: 1 per second;Response time: 15 sec in slowly moving air at 25�C (77�F);Temperature accuracy: +/- 2�C (+/- 3.6�F) at -40�C to -10�C (-40�F to 14�F) and +/- 0.5�C (+/- 0.9�F) at -10�C to 85�C (14�F to 185�F);RH accuracy: +/- 5% RH 0-90% noncondensing; +/- 8% RH over 90%;RH stability: +/- 1% RH typical at 50% RH in 5 years;Power consumption: 15 mA (normal) 1.0 mA (suspend mode);Maximum CAT 5 UTP cable length: 152.46 m (500 ft);Maximum USB cable range: 5 m (16.40 ft);Base unit operating temperature range: 0�C to 65�C (32�F to 149�F);Sensing device operating temperature range: -40�C to 85�C (-40�F to 185�F).
