The Fluke 787B ProcessMeter™ doubles your troubleshooting capabilities by combining the power of a safety rated digital multimeter and mA loop calibrator into a single, compact test tool. Based on the trusted measurement capabilities of the Fluke 87V meter, the 787B adds the ability to measure, source and simulate mA with the accuracy and resolution you would expect from a Fluke mA loop calibrator, giving you the ideal tool for troubleshooting and calibrating current loop applications. 

With Fluke Connect® mobile app and desktop software compatibility, technicians can wirelessly monitor, log, and share data from the field with their team anytime, from anywhere.* If you’re looking for even more troubleshooting power, the Fluke 789 ProcessMeter™ offers technicians even more flexibility, and even includes a built-in 24 V loop power supply.

*Requires Fluke IR3000FC module (not included). Not all models are available in all countries. Check with your local Fluke representative.

The Fluke 787B not only allows you to source, measure and simulate 20 mA DC current but also allows you simultaneously look at mA and percent of scale readouts so you can easily compare readings to what you see on your controller. Manually step mA signals (100%, 25%, Coarse adjustment, Fine adjustment) or use the Auto step and Auto ramp feature to work even more efficiently.

Designed to meet 1000 V IEC 61010 CAT III and 600 V CAT IV standards, the Fluke 787B is also a full-featured, precision, true-rms digital multimeter with standard features for diode testing and a continuity beeper. Troubleshoot more, while carrying less. The 787B also allows you to make frequency measurements to 20 kHz and includes Min/Max/Average/Hold/Relative modes for easy operation. Even the batteries and fuses are easily accessible allowing you to make fast, easy changes.

HM Digital DM-2
Commercial In-Line Dual TDS Monitor

Quality Product ~ Designed in USA and Korea

The DM-2 is a commercial grade monitor measuring TDS feed (input) water vs. product (output) water of a water filtration system at any time. With its shielded cables and diagnostic messaging this robust device is ideal for Reverse Osmosis (RO), Deionized water (DI) filtration systems that work well in applications such as drinking or potable water, Water treatment, Aquariums, Hydroponics and many more.

Highly efficient and accurate due to its advanced microprocessor technology

Displays TDS levels of the Feed Water and Product Water with in & out electrode probes

Auto-Off function conserves battery power (Shuts off automatically after 3 minutes)

Factory Calibrated: our meters are calibrated with a 342 ppm NaCl solution. The DM-2 features digital calibration.

Comes equipped with two 1/4 inch (1/4"x1/4"x1/4") or two 1/2 inch (1/2"x1/2"x1/4") T-fitting

Designed for commercial/industrial applications

Digital calibration can be done individually on each line.

Improved design, including an extra-large, easy-to-read LCD display

1000 to 9990 ppm, the resolution is in 10 ppm increments, indicated by a blinking ‘x10’ image.

Cable Length: 46″ (including sensor), shielded cables

Sensor: Dual, 1/4″ diameter for quick-connect fittings

Digital Calibration: Digitally factory calibrated to NaCl 342 ppm. Re-calibration can be done separately for each line.

Power source: 2 x AA batteries (included)

Size: 11.6 x 6.8 x1.8 cm (4.6 x 2.6 x .7in.)

CO/Temp Meter (with adjustable alarm)
Measures of Carbon Monoxide and Temperature
(Model No.: TM- 801)

TM-801 CO meter is used for measuring the CO levels upto 1000ppm.

Carbon monoxide (CO) is a poisonous gas that has no smell, color or taste. But it is very dangerous and reduces the oxygen-carrying capacity of blood that causes you unwell, illness and death.

Temperature range: -20~50 ºC (-4~122 ºF).

Dual and digital display of the CO and temperature measuring

Adjustable alarm: Adjustable alarm threshold level (25 /35 /50 /100 /250 /400 /800 /Randomly adjustable); Enable/Disable alarm

Power supply: 1.5V UM-4(AAA) battery × 6 PCS or AC100~240V or DC Adaptor 9V/0.5A(9mm).

Operating Temperature & Humidity: -20°C to +50°C, <80% RH.

Storage Temperature & Humidity : -10°C to +50°C, <70% RH.

Weight: approx 250g (Batteries not included).

UM-4(AAA)1.5V battery ×6 PCS, user’s manual, carrying pouch.

Carbon monoxide content in the air | Inspiration time | Symptoms and applicable standard

9 ppm : Maximum indoor air quality level.

35 ppm | 8 hours : The average exposure level per U.S. OSHA workplace standards.

50 ppm | 8 hours : The maximum average exposure of the U.S. OSHA workplace standards.

0.01%(100 ppm) | 2~3 hours : Evacuate people from enclosed space if the CO concentration exceeds 100 ppm per OSHA exposure limit. Mild headache.

0.04%(400 ppm) | 1~2 hours : Headache occur in 2.5 hours to 3.5 hours.

0.08%(800 ppm) | 45-min : Dizziness, nausea, cramps(convulsions).

0.16%(1600 ppm) | 20-min : Headache, dizziness and will be dead within 2 hours.

0.32%(3200 ppm) | 5~10 min : Headache, dizziness, vomiting and will be dead in 30 minutes.

0.64%(6400 ppm) | 1~2 min : Headache, dizziness and will be dead within10 to 15 minutes.

1.28%(12800 ppm) | 1~3 min : Cause death.
