37803-86 Traceable Digital Thermohygrometer with Dew Point, Memory Card, and Calibration by Digi-Sense

This thermohygrometer records data onto a standard SD memory card instead of built-in memory - the advantage being that when the memory on the SD card is full, the SD card can be simply exchanged out for unlimited data storage. The data is provided in a text report that includes date, time of day, and readings of sensors, and may be sent to any spreadsheet or database.

The unique 4-line display simultaneously shows ambient temperature, humidity, dew point, and time of day. An audible and visual alarm alerts you when temperature, humidity, or dew point levels are higher or lower than the programmable set points. User-settable parameters include date, time, sampling time, temperature unit of measure, high/low alarm set points, and auto power off.

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
• SD memory card stores up to 5.9 million readings
• Adjustable data logging sampling time from 1 second to 12 hours
• Maximum and minimum readings can be recalled or stored for later use

Includes

SD memory card, USB memory card reader, magnetic mounting strips, hook and loop mounting strips, bench stand, power adapter, three AA batteries, and NIST-traceable calibration certificate with data.

0635 9532 Vane Probe (Ø 16 mm) Fixed Cable by Testo

Use the vane probe with the compatible testo multifunction measuring instrument (please order separately) to determine air velocity and volume flow.

Vane probe - features

Use the fixed cable to connect the vane probe to the measuring instrument. The probe is equipped with a telescope, which can be extended to a maximum length of 0.85 m. The immersion depth is easy to read off thanks to the scaling on the telescope.

The clearly structured measurement menu for volume flow makes the measuring instrument intuitive to operate. The volume flow is precisely calculated thanks to convenient input of the size and geometry of the duct cross-section. Timed and multi-point mean calculation, average volume flow, current reading and min./max. values are displayed in the measuring instrument.

Intelligent calibration concept

You will get exceptionally accurate measurement results with the digital probe, because the measuring instrument makes measurement uncertainty a thing of the past. You only need to send the probe in for calibration - so the measuring instrument remains in continuous use.

Areas of application for the hot wire probe

Ventilation ducts: Use the vane probe to measure air velocity in ventilation ducts with reliability. Benefit from fast calculation of the volume flow: in the "volume flow" measurement menu of the compatible measuring instrument (please order separately), configure the dimensions and geometry of the duct cross-section - the measuring instrument shows you the volume flow straight away.

• Intuitive: parallel determination of air velocity, volume flow and humidity
• Precise: accurate measurement results from +0.6 to +50 m/s
• Convenient: integrated telescope that can be extended to 0.85 m, with scaling, makes it easy to measure in any cross-section
• Intelligent calibration concept

Includes:

Vane probe (Ø 16 mm) with fixed cable (cable length 1.7 m), including telescope (can be extended to 0.85 m) and calibration protocol.

MW805 pH/EC/TDS/Temp Portable 4 In 1 Logging Meter by Milwaukee

This Milwaukee MW805 MAX pH/EC/TDS/Temp. 4-in-1 combo meter allows you to measure pH, EC (conductivity), TDS and Temp. with a single meter and one single probe.

WHAT PEOPLE ARE SAYING

• "Features look Great! Can't wait to order!
• "Great customer service, I have other Milwaukee meters."
• "These prices are unreal!"
• "Logging feature will be awesome!"

SUMMARY

pH and conductivity are critical for growers. pH can effect plant nutrient and water uptake and reduce the efficiency of fertilizer, herbicides and pesticides. Managing conductivity helps growers pinpoint fertilizer and other needs.

The Milwaukee MW805 MAX Combo Meter lets you easily and accurately test pH, conductivity and total dissolved solids (TDS) using a single meter and integrated probe.

Simple, portable and rugged. No more juggling multiple electrodes and wires. Automatic temperature compensaton included.

The MW805 MAX is the ultimate solution for pH and nutrient management.

DESIGN FEATURES

The design of the MW805 MAX is focused on simple operation and ruggedness. With a single probe, big screen, easy calibration, the MW805 is exceptionally simple to operate.

A tough meter build and a rugged but replaceable probe means that you can expect years of use.

The Milwaukee Combo meter offers:

• pH, conductivity / nutrient EC, TDS (ppt) with automatic temperature compensation.
• Selectable TDS factors from .40 to 0.8; defaulet value 0.50.
• Stability indicator prompting the user when the readings stabilize.
• Dedicated GLP key to store and recall data on system status.
• A replaceable, Amplified Combination pH/EC/TDS/Temp probe with a single 3 foot cable (1 meter) for easy use (MA852D/1 probe included)
• A cloth junction on the pH sensor to reduce contamination when measuring fertilizer solutions. Gel filled for long lasting measurments.
• A light weight and portable form factor at just 9.2 ounces (260 g) with battery and just over 3 inches wide.
• A large easy to read display.
• Factory calibration for Temperature and simple, highly accurate, single cell automatic, one point calibration for EC and an automatic up to 5 point calibration for pH.
• IP 67 rated rugged case built for field or lab applications.
• Specialized design for hydroponic, aquaponic, and greenhouse growers.

CARE AND USE

The MW805 MAX Combo Meter includes both a pH and EC sensor in the MA852D/1 integrated probe. Both need maintenance. Properly maintaining your probe will give you fast, accurate results for longer. All pH sensors have a limited life and response time gets longer with age. EC sensors are more robust but can still be affected by residue build up.

Here are our top four tips.
1. Always store with the cap full of buffer or storage solution not water.
2. Clean your probe regularly by soaking in cleaning solution.
3. Calibrate after cleaning and/or storage before testing to adjust for changes in the pH and EC sensor.
4. Gently stir the probe in the sample for a faster result.
