EXTECH Manuals

This Extech PH100 ExStik pH Meter has a waterproof design and can measure pH in liquids, semi-solids, and solids. It features a flat surface electrode that prevents electrode breakage or clogged junctions. Additionally, it has a RENEW indicator and CAL alert that reminds you when to replace your electrode and recalibrate. This pH meter also has 15 record and recall functions, 1, 2, or 3 point calibration that automatically recognizes buffer solutions, and an automatic temperature compensation function.

This user guide introduces the functions and operation of the Extech Oyster Series splash-proof pH/mV/Temperature Meter. The instrument can simultaneously display pH or mV and Temperature (°C/°F selectable), and can store 25 labeled readings for recall at a later time.

ExStik ® EC500 pH/Conductivity/Total Dissolved Solids (TDS) / Salinity meter is a device that measures PH, conductivity, total dissolved solids (TDS), salinity, etc. The EC500's dynamic cell-constant technology makes it possible to measure a wide range of Conductivity, TDS, and Salinity with the same electrode.

The document introduces a combination rugged flat surface pH electrode from Extech Instruments Corporation, which features flat surface technology for quick on-the-spot pH measurements combined with autoranging high accuracy conductivity cell. The product measures 5 parameters including conductivity, TDS, salinity, pH, and temperature using one electrode. It has various features such as adjustable conductivity to TDS ratio, RENEW feature, auto power off, and low battery indicator. The product is waterproof to IP57 and includes electrode, protective sensor cap, sample cup with cap, and neckstrap. The EC510 kit also includes conductivity calibration standards and pH buffer pouches.

This document describes a user-friendly and cost-effective testing kit introduced by Extech Instruments Corporation in 2007. The kit can measure 6 parameters including Dissolved Oxygen, pH, Conductivity, TDS, Salinity, and Temperature. It is designed for professionals in water, wastewater, groundwater, aquaculture, and fisheries industries.

This document describes the features and characteristics of Extech's pH, mV, and temperature meter, including measurement range, resolution, and accuracy.

The Extech 407228 Rugged pH/ORP/Temp Kit features a large 1.4-inch (36mm) LCD display that can show pH or mV and temperature (°C/°F) simultaneously. The meter has easy 2-point calibration (pH 7) and slope (pH 4 or pH 10) adjustments, along with a low battery indicator, Min/Max/Avg, auto-off and data hold. It has a built-in RS-232 PC interface and can be optionally equipped with the 407001 Data Acquisition Software and 380340 Datalogger. The kit includes the meter, mini pH electrode (60120B) with 39-inch (1m) cable, temperature probe (850188), protective holster with stand, and case.

This document is the user's guide of Extech Oyster Series meter, which introduces the functions and features of the device and how to use it.

This document describes the features and characteristics of the pH/Conductivity/TDS/ORP/Salinity Meter produced by Extech Instruments Corporation in 2009. The product can be used in the lab or in the field.

This document is the user manual of HW30 Heat Watch. It introduces the functions and operation methods of the device.

This document provides specifications and features of the CTH10 Radio Controlled Wall Clock Hygro-Thermometer. The wall clock receives time code from the NIST Radio Station WWVB and automatically adjusts the year, date, day, hour, minute, second, and daylight savings time. It features a large LCD display, super large 4.3-inch digit clock display, signal strength indicator, and alarm clock function. The clock can be used on desktops or mounted on walls.

This manual describes the functions and usage of the Extech Humidity Alert II Remote Probe Hygrometer. The device can measure temperature and humidity, and it emits an alarm when the %RH exceeds a preset high or low limit. The manual also describes how to adjust humidity and temperature and how to use the wall-mounted stand.

This document introduces Extech's Humidity Alert Humidity Indicator with Dew Point and Programmable Hi/Lo %RH Alarms. It also features Humidity and Temperature calibration adjustments.
