E Instruments Mini CO Sniffer 7898 is a personal safety ambient CO Monitor. The mini co sniffer 7898 is a hand-held, accurate, highly sensitive tester with LED scale and beeper. During operation a "confidence" beep is continuously present to assure the operator of the active safety surveillance. The gas concentration is marked using a 5 red LED bar and a proportional frequency buzzer.

E Instruments Mini GAS Sniffer 7890 is a rugged, highly sensitive mini co sniffer tester with an LED scale and beeper to effectively pinpoint small leaks of gaseous Hydrocarbon fuels from piping or appliances. Inaccessible points can be reached with the co sniffer 7890's 8" long flexible probe.

E Instruments Mini Refrigerant Sniffer 7892 is a rugged, sensitive, easy to use refrigerant sniffer for gas leak detection in refrigerant circuits and appliances. Inaccessible points can be reach with the refrigerant sniffer 7892's 8"long flexible probe.

Extech 451112-NIST- NIST Calibration Certificate Big Digit Thermo-Anemometer features: Multifunction Air Velocity Meter with wide temperature range; High accuracy via low friction ball bearing vane wheel on 39" (1m) cable; Utilizes a Type K sensor for temperature measurements, etc. Discontinued product.

Extech 461825-NIST Photo Tachometer and Stroboscope Combo features 2 meters in one: a Stroboscope, to examine rotating objects, and Tachometer to measure RPMs. The Stroboscopes

Features

Specifications

Extech 461830-NIST StroboTach Digital Stroboscope and Tachometer can freeze readings, without contact, from rotating objects so they can be analyzed. RPMs are displayed on a 4 digit LED screen. It examines motion and speed by simply targeting and synchronizing its flash rate (fpm) with a rotating object.

Extech 461891-NIST Contact Digital Tachometer High Precision measures fast and accurate RPM and surface speeds measurements by preforming contact measurements on rotating objects.

Extech 461893-NIST Digital High Precision Photo Tachometer can make non-contact RPM measurements by using the reflecting tape on a rotating object to point the integral light beam or laser.

Extech 461895-NIST Contact and Photo Tachometer Combo Meter combines a contact and non-contact meter for use in all applications. Depending on the contact or photo mode, the characters on the display will reverse.

Extech 461923-NIST- NIST Calibration Certificate - Laser Photo Tachometer features: Make non-contact rpm measurements of rotating objects; Use reflective tape on object to be measured and point the integral light beam or laser; 461923 Laser model can measure up to 6.5ft (2m) away from target, etc.
