TDS Testing Meter
Features:
- Graphite electrodes
- ATC
- Simple one point calibration
- Easy to use
- Economical
DiST® testers are reliable, pocket-sized instruments that will give you quick and accurate readings of conductivity and TDS.
This popular line of Dissolved Solids Testers have been redesigned to offer a host of improvements. They are widely used for monitoring EC/TDS in drinking water, water conditioning, reverse osmosis, cooling towers, wastewater, laboratories, agriculture, aquaculture,and aquariums, hydroponics, and the printing industry.
The casing has been modified to provide increased strength, a better fit for holding and a large LCD for easy viewing. The graphite sensors provide better repeatability since they do not oxidize. The casing has been engineered to allow air bubbles to escape. The temperature sensor is exposed to provide faster response time.
This tester features an amperometric graphite electrode that provides better repeatability in measurements since they do not oxidize. An amperometric measurement of TDS is based on Ohm’s Law, I = V/R where R depends on the distance between two pins and their surface. Oxidation changes both the distance and surface which will affect accuracy. The DiST’s non-oxidizing graphite pins are able to provide an optimal surface for accurate, dependable results.

Heavy Duty Waterproof pH Meter
Features:
- User-selectable calibration time out
- Automatic calibration
- Automatic Temperature Compensation
- Tutorial messages on LCD
- BEPS (Battery Error Prevention System) alerts the user in the event that low battery power could adversely affect readings
- Battery % displayed on startup.
The HI 9124 is a waterproof pH meter. A large dual-level LCD displays both the pH and temperature along with an operational guide. Graphic symbols are displayed to help the users during the calibration process.
The pH calibration procedure is automatic with five memorized pH buffer values
and buffer recognition to simplify the calibration process.
This meter utilizes the HI 1230B double junction pH electrode. The double junction helps to minimize junction contamination for accurate, consistent results.

COD Test Tube Digestion Reactor
Features:
- Low temperature alert appears when the block is warming up. It alerts the user that the temperature is below the set value.
- High temperature alert appears when the block is warming up. It alerts the user that the temperature is above the set value.
- Countdown timer shows time remaining until the heating element shuts off.
The HI 839800 COD reactor is constructed of durable materials. The aluminum block incorporates a 25-vial capacity and a well for a reference temperature probe.
The HI 839800 COD reactor is an easy-to-use test tube heater. Its well-marked user interface provides intuitive operation. The reactor is equipped with two predefined temperature settings: 150°C and 105°C. COD and total phosphorus digestions are conducted at 150°C, and total nitrogen digestions are at 105°C.
In addition, the HI 839800 has 3 LED’s for visual indication. A green LED indicates power, a blinking red LED warns the user of a hot heater block (above 50°C), and a yellow LED indicates heating.
A three-hour countdown timer is also incorporated to control timed digestions. When the countdown timer expires, a beep will sound and the heating element will turn off.
The reactor contains a thermal fuse that prevents overheating by turning off the heating element.
Block temperature is continuously displayed on the LCD even when there is no active temperature program running.
Please Note: An optional labortory bench safety shield, HI 740217, is highly recommended for use with the reactor to provide added safety in the event of overheating.
