PBX-310 3-Port Sensor Manifold by Agrowtek

PBX sensor manifolds integrate water-tight gland fittings into a 1" PVC manifold for sensing pH, conductivy, ORP and water temperature inline with a recirculating pump. Compression glands have a rubber insert that clamps around the probes when tightened. Manifolds make it easy to install and remove probes for calibration and maintenance.

Available in 2, 3 or 4 port configurations. Max: 60psi, 30gpm.

Measuring Range: -22 to +194°F

Measuring Range: -60 to +130 °C

Part Number: H197125LA

MW10 Free Chlorine Mini-Colorimeter by Milwaukee

The revolutionary new range of Milwaukee handy photometers are compact and easy to use, have a modern design, and measure Free Chlorine (MW10); Total Chlorine (MW11); Phosphate (MW12); Iodine (MW13) and Iron (MW14). Their main advantages are the small size, and the real simplicity when doing measurements on the spot. Within a few minutes you can get the required result on the LCD and the instrument directly displays the concentration of the specific component in ppm. The meter automatically turns off after 2 minutes in order to save the battery.They work exactly the same way as the other Milwaukee photometers:

When specific reagents are added, the water sample takes on a degree of coloration that is proportional to the concentration of the parameter being measured. The photometer measures this coloration. When a light beam passes through the coloured sample, energy with a specific wavelength is absorbed by the test substance. The photometer determines the coloration of the sample by measuring the transmission or absorption of light of this wavelength. The photometer then uses a microprocessor to calculate the concentration and displays the result.

The field of application is really wide including agriculture, drinking water analyses, aquariums, swimming pools or fish farms. As a result of this versatility and the affordable price it is undoubtedly worth using these products.

LED-Xset Flashlight and dual holder for oblique lighting at multiple angles by Zarbeco

Our portable specially modified LED Flashlight with double flashlight holder allows portable hands-free side lighting for MiScopes or other digital microscopes. Turn LEDs off on MiScope (MiScope with on/off switch), MiScope Megapixel 3, MiScope Megapixel 3 Extended Field, or MiScope Megapixel 4k, and use the flashlight for raking light for better texture and colors in an image. The flashlight has a powerful bright white light and is specially modified for longer and brighter imaging. It comes with AAA battery.

98766-84 Traceable Thermohygrometer with Memory and Calibration by Digi-Sense

This precalibrated humidity and temperature meter is ideal for routine or round-the-clock measurements in quality-control and critical environments. Obtain minimum and maximum temperature and humidity readings in labs, hoods, clean rooms, coolers, stockrooms, incubators, environmental chambers, and chemical storage areas. Monitor conditions overnight, on weekends, or for any time period.

Unit continuously displays current conditions, simultaneously, from a range of 25 to 95% RH and 32 to 122°F (0 to 50°C). Obtain instant readings - the solid-state sensors show changes in less than 30 seconds. Display updates once per second.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Fulfills CLIA requirements for monitoring temperature and humidity
• Read and clear MIN/MAX temperature and humidity measurements
• Switch between °F and °C temperature readings

Includes

Hook and loop tape for versatile mounting, bench stand, two AA batteries, and NIST-traceable calibration certificate with data
