The Extech DO610 DO/pH/conductivity kit has all the tools and accessories needed to measure 6 parameters
including: dissolved oxygen, pH, conductivity, TDS, salinity, and temperature. The Extech DO610 DO/pH/conductivity
kit features two meters as well as all the accessories you need to make precision water quality measurements:

Extech DO600 Dissolved Oxygen Meter

The highly accurate Extech DO600 dissolved oxygen meter displays oxygen levels either as percent saturation
from 0 to 200%, or as concentration from 0 to 20ppm (mg/L). The Extech DO600 dissolved oxygen meter features
adjustable altitude compensation from 0 to 20,000 feet in 1,000 foot increments as well as adjustable salinity
compensation from 0 to 50ppt.

The Extech DO600 dissolved oxygen meter offers a number of features which make this meter a versatile tool.
A large digital display with an analog bar graph indicates sample trends, and an internal memory stores up to 25
data sets for easy recall. The Extech DO600 dissolved oxygen meter also has data hold, auto power off and low
battery indication functions. The Extech DO600 dissolved oxygen meter self calibrates when it is powered up. Basic
accuracy is ±2% FS.

Extech EC500 pH/Conductivity Meter

The Extech EC500 pH/conductivity meter is a waterproof, handheld meter that combines a rugged flat surface pH
electrode with an autoranging high accuracy conductivity cell. By incorporating Extech’s dynamic cell-constant
technology, the Extech EC500 pH/conductivity meter measures five parameters including conductivity, TDS, salinity,
pH, and temperature using one just electrode.

Offering a number of advanced features, the Extech EC500 pH/conductivity meter features 9 units of measure: pH,
µS, mS, ppm, ppt, mg/L, g/L, °C and °F. An analog bar graph indicates trends and an internal memory
stores up to 25 labeled readings. The Extech EC500 pH/conductivity meter has an adjustable conductivity to TDS
ratio from 0.4 to 1.0 and a 0.5 fixed salinity ratio. Extech’s RENEW feature alerts users when to check calibration
and when the electrode needs replacement.

The Extech DO610 DO/pH/conductivity kit includes: an EC500 pH/Conductivity meter; a DO600 dissolved oxygen
meter with a replacement membrane cap; sample pH buffers (single use pouches for pH4, pH7, pH10); rinse solutions;
weighted base; 2 sample cups with caps; four 3V CR-2032 batteries; a neck strap for each meter; and a carrying case.
