Environmental Monitors
Environmental Monitor
This single instrument measures Humidity (RH),
Temperature ( ºC, ºF), Ultra Violet (UV)
and Visible Light (Lux)
The Environmental Monitor’s large 8-line display
allows the user to select more advanced
functions. Data logging functions enable over
10,000 readings, of all four parameters, to be
automatically taken at selectable intervals (every
10 seconds to 1 hour). The saved data can be
transferred to a computer by a wireless infrared
link (IRDA compatible). Most modern computers
have an infrared interface built in. For those that
do not, adaptors are available. The software is
provided, to save the logged data in a CSV format,
that can be accessed and displayed by many
applications (e.g. Microsoft Excel). Maximum and
minimum values, and their time measurement, are
displayed for each parameter. A kit is available, for
user calibration of the RH sensor, using saturated
salt solutions. Software compatible with Windows
7, Vista, XP. (Not compatible with Mac). Wt: 165g.
Dimensions: 5-7/8” x 2-9/16” x 1” (includes probe).

Power Supply:
• 2 x alkaline AA type batteries (not included)

UV Light Monitor 7640
The 7640 will measure UV present (µM/
Lumen), the total amount of UV (µM/M 2 )
and the amount of visible light present
(Lux or Foot-candles). This monitor is
similar to the M684-764, but without
humidity and temperature sensors.

• Visible Wavelength: 400 to 700nM
• Visible Power: 0.1 to 200,000 Lux
• UV Wavelength: 300 to 400nM
• UV Power: 2 to 50,000 µW/M 2
• UV Proportion: 0 to 10,000 µW/Lumen
• RH Range: 0 to 100%
Display Resolution:
• Lux: 0.1 up to 100 then 1.
• Foot-candles: 0.1 up to 100 then 1
• UV: 0.1 up to 100 then 1
• Proportion of UV: 1 µW/Lumen
• Temperature: 0.1ºC or ºF
• RH: 0.1%
Accuracy:
• Light and UV: 5% ±1 displayed digit
• Temperature: ±0.5ºC (±0.9ºF)
• RH: ±2.5%, 0-90% otherwise ±5%
Logging:
• Intervals: 10 sec(30 hrs), 1 min(7.5 days),
10 mins(75 days), 1 hour(454 days)
• Capacity: 10,900 readings all 4 parameters

Water Alarm
Alarm sounds when water comes in contact with remote sensor. Sensor
and alarm come connected with 6’ of wire (replaceable with up to 50’ of
wire) so the alarm continues to sound as water levels rise. Sensor unit
can be placed flat or suction-cupped perpendicular to the floor. Alarm unit
can be table, shelf or wall mounted (via hang-up key slot). 85dB alarm
sounds for up to 3 days. Circuit test bar ensures the system is
functioning. Unit sounds a warning tone when the battery is low.

Digital Psychrometer
This digital psychrometer is the most accurate evaporative type
psychrometer available today. Automatically holds the readings for 4
seconds while the probe is still in motion, eliminating errors due to
changes while reading. Easy to read 0.5” high LCD display.
Specifications:
