COMPUTERIZEDSYSTEMSPORTABLESAll of IST’s portable instruments are designed to operateon either alkaline or nicad batteries, or the ACadapter/charger which is included with every unit. TheAC adapter/charger will charge nicad batteries, whilebypassing alkaline batteries, and allows portable units tobe powered on at all times and ready for use for maximumreliability.REMOTE-LINK SYSTEMThe Remote-Link System is a state-of-the-art, computer-controlledgas monitoring system which allowssensors to communicate with the Remote-Link Computerover an AC power line, providing a data highway whicheliminates the individual sensor wiring associated withconventional monitoring systems. Since 1989, theRemote-Link System has provided customers worldwidewith the most advanced monitoring system available,with the capabilities, features, and field proven reliabilityfound on no other system. The Remote-Link’s powerfulmonitoring software includes such features as dataarchiving and reporting, curve plotting, alarm processing,and fault monitoring. Additionally, computergraphics display your plant and the locations of all sensorswithin your plant. By using the mouse button topoint and click on a sensor, you can view it’s currentreading and alarm status. A separate readings screen letsyou view the readings of all sensors simultaneously.When an alarm occurs, audible and visual indications areprovided and the graphics display will pinpoint thealarm area. In addition, programmable alarm relays areactivated to trip horns, lights, etc.The Remote-Link Systemcan accommodate hundreds,even thousands, ofsensors, yet is still an economicalchoice for systemswith as few as 8 sensors.The modular design of thesystem enables additionalsensors to be added withease at a low incrementalcost, allowing you to expandthe system accordingto your needs. Computerassisted calibration takesthe hassle out of calibration.Zero every sensor inthe system with the pressof a button! Then, simplyapply gas to each sensorand the let the computer dothe rest. Calibration justdoesn’t get any easier!TLV PANTHERThe TLV Panther is an Industrial PrecisionPhotoionization Detector (PID).

PORTABLES4 GAS, CONFINEDSPACE ENTRYPORTABLEMODEL IQ-200IST’s Model IQ-200 requiresjust two sensors for confinedspace entry applications, asingle solid state sensor forCO, H 2 S, and combustiblegases, and an electrochemicalsensor for oxygen. This makes theIQ-200 much more affordable than comparable confinedspace entry portables. Additionally, both the solid stateand oxygen sensors used in the IQ-200 are long-life sensors.Typical life expectancy is 5 years for the O 2 sensorand over 10 years for the solid state sensor. This results ina tremendous savings in long term operating costs associatedwith sensor replacement.The IQ-200 has an audible alarm buzzer, and alarmLED’s indicate low, mid, and high alarm levels for thesolid state sensor, and low and high alarms for the O 2 sensor.The IQ-200 does not incorporate a sample pump andsamples by diffusion only. It is small and lightweight,weighing just 22 ounces, including batteries. It operateson 4 size ‘AA’ alkaline or nicad batteries, or the ACadapter/charger. Carrying case is included.GAS SENSORSIST offers 5 different types of sensors: SolidState, Infrared, Photoionization, Catalytic Bead, andElectrochemical. This gives you the flexibility to choosethe best sensor(s) for your particular application. A briefdescription of each sensor type follows:SOLID STATESolid State sensors are made of a heated metal oxidematerial which temporarily changes resistance in thepresence of gas. Solid State sensors are available for thedetection of over 150 different toxic and combustiblegases, in ranges from low ppm %LEL. A list of gases andranges appears on the back of this brochure. Solid Statesensors come with a 3 year warranty, and have a life expectancyin excess of 10 years.INFRARED SENSOR (IR)Infrared (IR) sensors detect gases that absorb light inthe infrared spectrum. Sensors for carbon dioxide (CO 2 ),carbon monoxide, and hydrocarbons (such as Methane,etc.) are currently available. IR sensors offer good selectivityand good lifetimes. Ranges for CO 2 are availablefrom ppm to 20% by volume, with the lower ranges offeringbetter resolution. CO is available in % volumeranges, and hydrocarbon ranges are available from %LELup to 100% by volume, depending upon the gas.PHOTOIONIZATION DETECTOR (PID)Photoionization detectors (PID) operate by ionizing thetarget gas with ultra-violet radiation, and then collectingthe ions across a high voltage plate which produces anelectrical signal proportional to the gas present. PID’soffer fast response for many Volatile Organic Compounds(VOC’s), including, among others, benzene, vinyl chloride,phosphine, and hexane.ELECTROCHEMICALElectrochemical sensors operate by producing a chemicalreaction with the gas of interest. Sensors are availablefor certain toxic gases in ppm ranges, including NH 3 , CO,Cl 2 , H 2 , HCl, HCN, H 2 S, NO, NO 2 , O 2 , O 3 , and SO 2 . Forsome of these gases, electrochemical sensors can offer afairly high degree of selectivity. Electrochemical sensorshave a life expectancy of 1 to 2 years and come with a 1year warranty.CATALYTIC BEADCatalytic Bead sensors operate by burning combustiblegases, raising the temperature of the sensor. This temperaturerise changes the resistance of the sensor andproduces a signal proportional to the gas concentration.They detect combustible gases in higher concentrations(above 1000 ppm) only. They are not selective and will respondto a wide range of combustible gases. However,since they only detect higher gas concentrations, they arenot prone to interference from many toxic gases. CatalyticBead sensors have a life expectancy of 2 years and comewith a 1 year warranty.1 2 3 4 51 IST’S PATENTED SOLID STATE SENSOR2 INFRARED SENSOR (IR)3 CATALYTIC BEAD SENSOR4 ELECTROCHEMICAL SENSOR5 PHOTOIONIZATION DETECTOR (PID)To help you select the most appropriate sensorfor your application, contact IST toreceive additional assistance and a copy ofIST’s Sensor Selection Guide.

The following gases are available for detection using IST’s Solid State Sensors. The full-scale ranges listed are standard rangesavailable. For toxic gas monitoring, ranges are typically chosen which are higher than the TLV so that hazardous levels will bedetected (TLV is defined as a SAFE level). For combustible gases, the typical range is 0-100 % LEL. Other ranges can also beprovided—please contact IST for information.
