Extech SDL800 Digital Vibration Meter/Datalogger is a multi-function instrument for measuring vibration amplitude, velocity and acceleration. It has a wide frequency range (10Hz to 1kHz), high accuracy (±(5% + 2 digits)), and easy data transfer to PC for analysis with SD card storage.

This document introduces the features and uses of Extech's Fruit Hardness Tester Model FHT200. The tester is used to measure the hardness (ripeness) of fruits such as apples, pears, strawberries, and grapes. It features a high-precision load cell sensor, digital display with peak hold function, tension or compression measurement, positive/reverse display, large backlight LCD display, RS-232/USB computer interface, and comes with a hard carrying case and 4 measurement tips.

This document describes the Fruit Hardness Tester FHT200 produced by Extech Instruments Corporation from 2008 to 2011. The tester features four penetrometer tips for large/hard and small/soft fruits. It has a basic accuracy of 0.5% and functions including tension or compression, peak hold, and zero. The large LCD display with backlight allows for easy readability. The tester can be connected to a computer via RS-232 interface and optional software is available. It comes with four penetrometer tips and six AA batteries.

This is the user manual of Extech CG204 coating thickness tester, which can measure the thickness of coating on non-ferrous metal and ferrous metal by magnetic induction and eddy current methods respectively.

Support USB interface, can connect computer for data recording. Includes Windows® compatible software, USB cable, wind cover, tripod, hard carrying case, AC adapter and 9V battery

TR100 Mini 7.5” Tripod is a compact tripod that is easy to carry and is made of durable lightweight construction. It is used with handheld meters or compact digital cameras with standard tripod mount feature.

The Extech SL130 Sound Level Alert with Alarm is a sound level detector and alarm device that can be used in industrial, hospital, auditorium, school and other places where it is necessary to be alerted when sound level reaches set point.

The Extech 407790 Real Time Octave Band Analyzer is an auto ranging Type 2 integrating sound level meter featuring 1/1 and 1/3 Octave Band real-time noise analyses. The 407790 offers five measurement parameters: SPL (Sound Pressure Level), Leq (Equivalent Continuous Sound Pressure Level), LE (Sound Exposure Level), Lmax (Maximum Sound Pressure Level), and Lmin (Minimum Sound Pressure Level). The built-in memory stores 12280 data records in sound level mode and 1024 records in Octave mode. The stored data can be easily transferred to a PC with the supplied software and RS-232 cable. This meter permits choice of ‘A’, ‘C’, or ‘Flat’ weighting and ‘Slow’ / ‘Fast’ response times. AC and DC analog output signals are available for chart recorders and other external recording devices. Careful use of this device will provide years of reliable service.

Extech 407764 Type 2 Sound Level Meter is a sound level meter released by Extech Instrument Corporation in 2008. The sound level meter has a measurement range of 100dB and can measure sound pressure levels from 30 to 130dB. It also has three frequency weightings: A, C, and Flat, and can choose fast response or slow response. The sound level meter can store 12280 data points and can transfer data to a PC via an RS-232 interface. It also supports 1/1 and 1/3 octave band analysis.

This manual introduces the features and usage of the Extech 407768 Sound Level Meter. This sound level meter has auto range measurement, programmable frequency weighting and time response, Min/Max Memory, Max Hold, Analog output and RS-232 PC Interface.

Extech 407768 Digital Sound Level Meter is a high-accuracy sound level meter that meets Type 2 standards and has a built-in RS-232 interface for capturing data directly to a PC.

This is an integrating sound level datalogger, model 407780. It has programmable integrating time, provides precise linearity over a wide range (100dB), and displays Leq, SEL, SPL, MAX-L and MIN-L measurements. Response time (FAST, SLOW and IMPULSE) and frequency weighting (A and C) are programmable. The analog output (AC and DC) can be used with headphones, chart recorders or other devices to store data. The 407780 with PC Interface and real-time calendar clock datalogs (stores) up to 32,000 readings for later transfer to PC. Careful use of this meter will provide years of reliable service.
