1.3 Description (continued)
Back-up Battery. The iServer comes with a universal 100 to 240 Vac power adapter.
A standard 9 Volt Alkaline battery (also included) allows the device to continue recording
data for 60 hours (at one minute interval setting) without external ac power (such as a
power outage).
Display and Chart Two Channels. The transmitter comes complete with a temperature
and humidity probe for measurement of a single location.
With the addition of a second probe, the transmitter can measure and display
temperature, humidity and dew point in a second location up to ten feet away.
The transmitter can display and chart absolute measurements in both locations, or a
differential measurement between the two locations. The second probe requires no
change to the basic transmitter hardware, it can be added at the time of purchase or in
the future. A choice of industrial probes in 2" and 5" lengths, and a wand style for ambient
indoor applications are available. A simple DB-9 "Y" connector is required for adding a
second probe.
Sensor and Calibration. It is not necessary to take the iTHX-SD out of service for
routine calibration. The temperature/humidity sensors are interchangeable and can be
replaced for about the same cost as a typical calibration. Replacement sensors with
optional 3-point NIST traceable calibration certificates are available.
Email Alarms. The device can trigger an alarm if temperature or humidity goes above or
below a set point that you determine. Your alarm can be sent by email to a single user or
to a group distribution list, including text messages to cell phones and PDA's.
Alarm Relays. The iServer features two 1.5 Amp relays. With the easy Web-based setup
page, the two relays can be programmed for any combination of temperature or humidity,
and high or low set points. The relays can also be programmed to remain latched and
require a manual reset if a limit is exceeded.
Link to Web CAM or IP Camera. The Web page includes a link to a "Web Cam" or "IP
camera" (not included). If you get a message about an alarm condition, you can quickly
click on the link to view the actual scene over the Internet.
