The Extech IR201A Pocket IR Thermometer is a compact and affordable non-contact infrared thermometer that measures surface temperature of objects that are difficult to reach or unsafe to contact. It features a wide temperature range from -4°F to 518°F, a built-in laser pointer, adjustable emissivity, and a 6:1 field of view.

The Extech 461950 Panel Tachometer is a panel-mounted digital tachometer that displays continuous readings from 5 to 99,990 rpm. Single pulse activation eliminates the need for special gears when setting up the meter in any given application. Models 461955 (proximity sensor) and 461957 (photoelectric sensor) are also covered in this manual. Careful use of these devices will provide years of reliable service.

The Extech 461950 1/8 DIN Panel Tachometer measures 5 to 99,990 rpm using optional Proximity or Photoelectric sensors. The instrument has microprocessor quartz crystal accuracy of 0.05% + 1 digit, resolution from 0.1 rpm (5 to 1000 rpm) to 1 rpm (1000 to 9999 rpm) to 10 rpm (10,000 to 99,990 rpm). The large 4 digit LED display updates once per second (rpm greater than 60). A unique design permits RPM measurements of a one hole gear or disk eliminating the need for special gears. A pulse is measured when a ferrous object (stud) passes by sensor. The instrument is powered by 115/230 VAC 50/60Hz.

The Extech 461960 RPM Controller/Monitor is a professional tachometer monitor and controller. It features a built-in control relay and alarm relay, which close when the measured value reaches the high or low alarm value and control value, respectively. It also has hysteresis value setting for control and alarm function, settable number of input pulses per revolution, and settable roller diameter for the surface speed function. It works with the optional proximity or photo sensor, has a large easy-to-read red LED display, RS232 computer interface for use with optional software, and a microprocessor circuit for high accuracy and special functions. Optional data acquisition software is also available.

This document provides ordering information for the RPM Controller/Monitor from Extech Instruments Corporation and its associated accessories. The controller/monitor offers various features and characteristics such as displaying RPM, surface speed measurement, control and alarm functions, etc. Additionally, the document includes specifications and technical parameters of the product.

This document describes the operating methods of Extech 461830/461831 digital stroboscope, including product features, operating steps and maintenance and repair.

The Extech Tachometer is a precision instrument for measuring rotational and linear speeds. This document provides specifications and features of two models of Tachometers. The 461700 Photo Tachometer uses precision optics and reflective tape to measure the RPM of rotating devices, while the 461750 Contact Tachometer uses convex and concave attachments to measure RPM and has a built-in wheel for measuring the linear surface speed of moving devices such as conveyors and treadmills.

Extech's Mini Laser Photo Tachometer, Model 461920, provides non-contact RPM and Revolution count measurements. The laser pointer beam provides accurate long distance measurements for photo tachometer measurements. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.

The Extech 461920 non-contact laser tachometer can measure the RPM of rotating objects. Use reflective tape on the object to be measured and point the integral laser to measure the RPM. The product also has the function of recording the last reading and recalling the minimum/maximum readings.

This document describes the features and characteristics of the Extech 461880 Vibration Meter and Combination Laser Tachometer, including vibration measurement and tachometer functions. The vibration measurement function includes measurement ranges for acceleration, velocity, and displacement, as well as peak, max hold, and frequency range functions. The tachometer function includes contact and non-contact RPM measurements. The product also features a 1000 point datalogger and auto power-off function.

This is a multifunction meter that can measure acceleration, velocity, displacement, RPM and linear surface speed.

This is a photo tachometer that can measure RPM and linear surface speed.

This is a user's guide for Extech's Combination Photo-Tachometer Stroboscope 461825, which introduces how to use the product.

This product is a combination photo tachometer/stroboscope that can measure speed and strobe speed.
