*Note:
Transition times are measured after a 2-hour soak at the respective start temperature with an empty chamber,
as indicated on the temperature controller, 23°C ambient. Measured with setpoint beyond the start and end
temperatures. Does not include the effect of proportional band when approaching setpoint.
Input Power
120 V nominal (110 to 126 VAC), 60 Hz, 1 PH
Max Current Draw 10 A, Recommended Minimum Service 15 A
Workspace Dimensions
13.8"W x 11.8"H x 11.8"D, 1.1 cubic feet
Outside Dimensions
Benchtop Model 101H-B
23.25"W x 36"H x 28.7"D (nominal), 200 lbs.
Floor-Standing Model 101H-F
23.25"W x 62.3"H x 28.7"D (nominal), 250 lbs.
Min. Installed Clearance
12" from the rear. Full access to left side is required for routine maintenance when
draining the internal water tank and changing the water filter. Full access to the top is
required to manually fill the internal water reservoir.
Access Ports
3" Port on left and right side (two total), Supplied with foam plugs
Sound Level
66 dBA (A-weighted, measured 36" from the front)
Air Flow inside Chamber
100 SCFM
Heat Load Into Room
2000 BTUH (Maximum rated chamber load at maximum cooling rate from high
temperature soak.)
Water Requirement
Built-in reservoir requires an initial fill of 1 to 2 gallons of Single-Distilled or De-
Ionized Water. Use of unfiltered tap water will damage the humidity system and void
the warranty. Built-in water recirculation system with filter returns condensate to
internal water storage tank.
May be plumbed to a source of Single-Distilled or De-
Ionized Water, maximum 50 psi. Negligible water consumption. Built-in water
recirculation system with filter returns condensate to internal water storage tank so no
drain line is required.
NOTE:
Performance is typical and based on operation at 23°C (73°F) ambient and nominal input voltage. This
product is designed for use in a normal conditioned laboratory. Operation at higher ambient temperatures will result
in decreased cooling performance. Operation above 30°C (85°F) or below 16°C (60°F) ambient is not
recommended. Due to continuous product development, specifications are subject to change without notice.
