EM802-EC-MB CS8000TC, Modbus 485 Blind Transmitter by Sensorex

The EM802-EC is our most cost-effective solution for connecting our S8000 series Contacting Conductivity sensors to a PLC or SCADA system. This small electronic module functions as a blind transmitter with a 4-20mA or MODBUS/RS485 output. No additional instrumentation is required to condition the sensor signal to be read by your PLC or SCADA. It can also be used to pair Sensorex sensors with any controller that has a 4-20mA or RS485 input card. Easily connects to our CS8300TC Modular Contacting Conductivity Sensor Package to form a complete monitoring solution.

• Blind 4-20mA or MODBUS/RS485 transmitter for connecting conductivity sensors to PLC or SCADA
• Small form factor saves valuable panel space
• Input Voltage Options: 12V DC MODBUS only; 24V DC 4-20mA & MODBUS
• Compatible with CS8300 conductivity sensor
• Compatible with PT1000 RTD temperature compensation

98768-53 Traceable Excursion-Trac™ Datalogging Low-Temp Thermometer with Calibration; 1 Stainless Steel Probe by Digi-Sense

Easily monitor temperatures overnight or for any time period - minimum and maximum temperatures are stored until the memory is cleared. Set high and low alarms in 1° increments; alarm sounds when temperature rises above or falls below set points. The alarm tracking feature stores data for up to 10 different alarm events detailing when the alarm state occurred, as well as when the unit returned within range. Alarm state indicator includes visual LEDs, audio alerts, and flashing LCD segments.

Transfer data recorded in a CSV format to any computer via a USB flash drive - no software is required. Simply clear memory after downloading data to USB drive. Unit continues to record new data while downloading old data. Other status indicators include low-battery, memory full, USB data transfer, and active alarm state. All probes are attached to a 10-ft (3-m) microcable that permits a door to close on it.

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.

Durable stainless steel probe withstands both low and high temperatures and are ideal for measuring temperatures of air, liquids, and semi-solids. Sensor stem measures 6.25"L x 1/8" dia.

KEY FEATURES

• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Memory can be cleared after downloading data and alarm events
• Set limits for and store up to 10 unique alarm events
• Smart-Alarm™ with visual/audible alarm continues to alert even if conditions return to normal range
• Triple-display - shows high, low, and current temperature simultaneously
• Ideal for monitoring ultra-low temperature freezers

Includes

Pt RTD stainless steel probe with 10-ft PTFE cable, flip-open stand, hook-and-loop strips, magnetic strips, wall-mount receptacle, batteries, and NIST-traceable calibration certificate with data.

MW804 pH/Conductivity/TDS/Temperature Tester with Replaceable Electrode by Milwaukee

The MW803 and MW804 are pocket testers with dual-level LCD that measure pH/ Conductivity/TDS/Temperature in one single tester!

The large display shows readings in an extended range from 0.00 to 14.00 pH and 0 to 3999 μS/cm, 0 to 2000 ppm (MW803), 0 to 20.00 mS/cm, 0 to 10.00 ppt (MW804) and simultaneously shows temperature from 0.0 to 50.0°C or 32.0 to 122.0°F. They have a stability indicator and hold function that freezes the display for easy and accurate recording. The large display also has graphic symbols to guide you through all operations. The EC/TDS conversion factor is user selectable as well as the temperature compensation coefficient (β).

Ideal for quick and accurate measurements in swimming pools, aquariums and horticultural applications they can also be used in Industrial and Laboratory applications such as cooling towers, food processing, plating, drinking and waste water etc.

52310 Hummingbird 9-27x56 Micro Spotting Scope by Celestron

The Hummingbird spotting scope shares many qualities with its namesake bird. In the wild, hummingbirds are known for their very small size, their agility (they can fly in most any direction at will), and their ability to travel long distances (many migrate between South and North America). The Celestron Hummingbird is the world's first "micro" spotting scope well suited for hikers, birders, and other wildlife watchers on the go.

• World's first micro spotting scope-fits easily in your vest/coat pocket, cargo pants, or shoulder bag
• 9-27x magnification range
• Comfortable 45° viewing angle
• Close focus distance of 10 feet
• Tripod adaptable for long-duration or long-distance viewing
• Durable, fully waterproof construction withstands bumps and jolts, wet/humid weather, and other environmental challenges

Go "Micro"

Standard spotting scopes tend to be large and/or heavy, making them inconvenient to carry long distances in the field. The Hummingbird will shatter your expectations for how lightweight and compact a spotting scope can be, so you'll take it places you never thought possible. You can easily hold this spotting scope in one hand, place it in a pocket, or pack it along in your carry-on luggage without compromising space.

Crisp, clear images

Although it is small, Hummingbird does not compromise on quality. All air-to-glass surfaces are fully multi-coated with high transmission optical coatings. The result is maximum light transmission for bright, sharp and contrast images. The prism is phase-coated BaK4, which increases contrast and resolution for sharper, more detailed images.

Durable, waterproof construction

The durable body of the Hummingbird works to keep the spotting scope protected against bumps and jolts both during transport and in the field. It's also fully waterproof and nitrogen-purged, so you can use the scope worry-free in downpours, humid conditions, and other environmental challenges.

Ready for any adventure

The Hummingbird 9-27x56 spotting scope features a close focus of 10 feet, making it perfect for viewing birds, butterflies, plants, or other nearby subjects. The magnification of the 9-27x56mm spotting scope spans the standard magnification ranges of both a binocular and a spotting scope. No matter how you choose to observe, this versatile spotting scope is an excellent all-around performer.

Ways to observe

Unlike most spotting scopes, Hummingbird is so small that you can use it handheld at the lowest magnification level for a quick view of your subject. Travelers who want to save space can replace both their binocular and their spotting scope with this one optic. But the scope is also tripod adaptable, so you can secure it to a stable platform for comfortable long-duration or long-distance viewing.

Hummingbird provides plenty of eye relief for use with or without eyeglasses. For use while wearing eyeglasses, leave the twist-up eyecup in the lowered position. For use while not wearing eyeglasses, twist the twist-up eyecup into the extended position.
