|Dimensions||TRI-1 alone is 3.5" (8.9cm) high x 16.75" (42.54cm) wide (19" (48.26cm) with rack mount hardware) x 12" (30.48cm) deep.|
|Weight||12 lbs.(5.5 kg.), 20 lbs.(9.1 kg.) shipping|
The femto-TECH TRI-1 digital remote allows the user to remotely monitor systems that are in hard to reach areas. The TRI-1 includes functionalites similar to it's parent U24-D system, including but not limited to two audio/visual alarms that can be set independent of the parent device, as well as outputs for remote data collection and logging.
Active Gamma Comp.Gamma compensation for 224x chambers
|Gamma chamber will match specs identical to chamber it is compensating for|
The femto-TECH Active Gamma Compensation Chamber is designed to be paired with comparable femto-TECH 224x chambers. The gamma compensation chamber is mounted on top of the chamber it is compensating for, and actively offsets any gamma radiation it detects from it's paired chamber's readings. The gamma compensation chamber can be deactivated at any time via a switch on the electrometer housing.

FT100 Filter AssemblyHEPA filter assembly with 99.9% efficiency
|Filter Material||P100 filter cartridge|
The femto-TECH FT100HEPA filter assembly is designed to hold a standard P100 filter cartridge such as the Mine Safety Appliances (MSA®) 815369. Other brand filters with diameters of 2.56” (65mm) across the main body and 2.73” (70mm) across the top edge are acceptable. These filters are effective in removing up to 99.97% of all particulate aerosols including oil-based aerosols under the 42 CFR 84 P100 classification. The assembly consists of two parts. The lid is attached with four (4) 1” 6-32 Phillips head screws. The main body has an o-ring for sealing the lid (1/16” x 2 7/8” x 3” #40) and another (3/32” x 2 9/16” x 2 ¾” #145) for sealing the replaceable filter cartridge. Any label on the side of the filter cartridge must be removed prior to installation in the main body (see picture below). Typically, a standard pair of pliers is required to remove the filter cartridge. Gently pulling on alternating sides eases removal of the filter. The inlet port in the lid and the exhaust port on the main body consist of fine thread NPT tapped holes for barbed 1/8” x 1/4” fittings. The lid may be removed and rotated to any one of the four possible alignments. Four threaded 6-32 holes are available for mounting with four on the bottom (3.25” center to center). Replacement of the filter is totally dependent upon the pumping time, flow, and the amount of contaminants. Either a predetermined schedule, such as once a month for continuous pumping, or by checking the flow rate periodically should guide the user as to how often to change. If the filter becomes restricted, a vacuum will be drawn on the ion chamber. A drop of less than 100 torr will not create a large error in the measured concentration. If an inline rotometer or other control is used to adjust flow, a drop in flow of 5% or greater may indicate the need for a filter change.
