Otis Instruments, Inc. products

The WireFree GenII View OI-9100 is a hand held signal strength meter specifically engineered to show the status of any WireFree GenII gas detection device within range. The View features a 4-line scrollable display. Using a 4-column read, the View is capable of revealing the Channel, Reading, Signal Strength, and Time Since Last Message of any WireFree device on site, as well as the Sensor, Gas, and Battery. The View contains a 2.4 GHz ISM, 100 mW radio, ensuring prompt and accurate communication with other WireFree devices. The ability of the View to continuously notify the user of each WireFree device`s status at a particular site make the device a truly phenomenal safety product to be introduced into the industry.

The Otis Instruments, Inc. GenII ProSafe 4x22 Model OI-7420 is a two channel gas monitor that functions as a transmission controller.  The OI-7420 monitors toxic, combustible and oxygen gas levels in ambient air by receiving and displaying 4-20mA signals from up to two wired sensor assemblies. The OI-7420 features a 160x104 graphical LCD display and is equipped with four “dry contact” (Form C) 5 Amp alarm relays (with 4 Amp fuses) that are full-scale adjustable. The OI-7420 operates with either 12-35 Volts DC or 110/240 Volts AC power-in and includes a Modbus output with optional real-time monitoring software. The ability to display data and activate alarms in relation to readings sent from on-site sensors make the OI-7420 a truly phenomenal product in the safety realm of the gas industry.

The OI-7010 is a Hybrid Monitor available with 12, 32, or 64 channels. The device supports up to 12, 32, or 64 WireFree sensor units, and up to four 4-20mA input sensors. The device is backward compatible with GenI WireFree sensor units, and also supports GenII Wirefree sensor units (configurable).

The Otis Instruments, Inc. Model OI-6000K Gen II ambient air gas sensor assembly is a 2-relay wired (Notis) sensor assembly that uses a Catalytic Bead, Electro-Chemical, PID, or Infrared sensor element to detect a variety of gases. 

The Otis Instruments, Inc. Model OI-6000 Gen II ambient air gas sensor assembly is a wired, WireFree, or “Notis” sensor assembly that uses a Catalytic Bead, Electro-Chemical, PID, or Infrared sensor element to detect a variety of gases. The device comes standard with a 102 x 64 graphical LCD screen, Otis Instruments standard three-button interface, Otis-blue custom explosion-proof enclosure, and non-intrusive magnetic switches.

The Otis Instruments Permian II Model OI-792 is a DC powered dual channel Hydrogen Sulfide Gas or Combustible Gas Monitoring system. The Permian II includes 2 Model OI-641 H2S Sensor Assemblies or 2 Model OI-130 LEL Sensor Assemblies, plus the OI-481 Strobe Light Alarm and OI-488 Audio Alarm, along with 25 feet of Sensor cable and 50 feet of power cable with battery clips. The Permian II is equipped with a digital display, dual alarm levels for Low and High alarms, and a fault indicator. Each alarm level uses 10 Amp relays, and has a visual LED indicator on the front panel. Both the Low and High alarms are adjustable full scale, and the High alarm is equipped with a High alarm disable switch.

The Otis Instruments, Inc. Model OI-520 Calibration Station is a precision gas blender that simplifies the calibration of air quality instruments. The OI-520 is able to blend a wide range of calibration gas levels from a single cylinder. This feature saves money by substantially reducing the number of calibration gas cylinders required and often eliminating the need for zero air cylinders. The OI-520 blends conditioned ambient air with a precisely controlled flow of an elevated concentration of toxic gas to provide the ppm level of the calibration gas desired by the user. The device also permits the use of conditioned ambient air—air from which interfering gases have been removed as an accurate “zero” air calibration gas, even in the presence of atmospheric contaminants.

The Permian II OI-WF792 is a self-contained wireless relay/alarm board, specifically designed for conjunctive use with the various components of the Otis Instruments, Inc. WireFree product line. The Permain II features automatic channel hold when either the low or high alarm is triggered, and can monitor up to two sensors. The Permian II requires 12-24 Volts DC and receives transmissions from WireFree sensors via an on-board 7 mile line-of-site 900MHz radio.

The Otis Instruments, Inc. GenII WireFree OI-6900 ambient air gas sensor assembly is a WireFree gas sensor assembly that uses an Electrochemical or Infrared sensor element to detect a variety of gases. The device comes standard with a 102 x 64 graphical LCD screen, Otis Instruments standard three-button interface, Otis-blue custom explosion proof enclosure, non-intrusive magnetic switches, and radio (900MHz or 2.4GHz). The OI-6900 is designed to be self-contained and to last from 6-12 months on a single battery (time varies depending of amount of gas detected). The device has been designed to reject EMI and other forms of interference in order to avoid false gas readings.
