93831-85 Penetrationation RTD Probe 100 Ohm ANSI 3-Blade Connector, 4" L 5ft Coil Cord by Digi-Sense

Maximum error for probe assembly is ±1.1°C + 0.12% of reading below 300°F, ±0.35% of reading above 300°F. Alpha coefficient is 0.003850 Ω/Ω/°C (DIN IEC 751). Resistance at ice point (0°C) is 100 Ω.

Note: Time constant is the time required to reach 63.2% of the new reading. To determine how long it will take to reach 99% of the new reading multiply the time constant by five.

Note: The temperature range is for the probe tip only. The handle material may be affected if the probe is rated higher than the handle depending on exposure time, application, and handle material. ABS handles are rated to 220°F (104°C); PVC handles are rated to 200°F (93°C); Stainless Steel handles are rated at 450°F (232°C); Mini Connectors are rated to 392°F (200°C).

• Time Constant: 1-3 seconds or greater
• Custom designs or changes to this product are available upon request

MTC-300 Automatic Variable Speed Control by Schaefer

Our broad range of sensors and manual/automatic controls allow dairymen, greenhouse operators, plant managers and others to control fans and heaters and optimize thermal comfort in their facilities.

VK24-CK-WSC 24" Cattle Kooler Circulation Fan, Cord, Special Mount, Wired Switch Cord by Schaefer

Reduce heat stress and improve air quality with Schaefer's uniquely designed circulation fans. Unrivaled in the market, these fans are engineered to produce greater air movement and superior cooling no matter the application. You don't hear them. You don't see them. You only feel them!

Also known as Horizontal Air Flow (HAF) fans, these fans move air in a coherent horizontal pattern creating a gentle 'racetrack' air flow pattern needed in greenhouses to maximize heat distribution and humidity control by mixing the air, from ceiling to floor.

S272CD/10/BNC Online Process pH Sensor, Flat, 3/4" NPT, PPS, 10ft, BNC by Sensorex

Our S272 series of pH and ORP sensors deliver reliable online monitoring for in-line or submersion installation configuration. Double-junction reference extends sensor lifetime by preventing contamination of the reference with sample components that interact with Silver (Ag). Minimal maintenance required due to the flat glass measurement surface, which also reduces the threat of measurement surface breakage. A versatile sensor for moderate and multi-purpose applications. S272 sensors come with a fully integrated cable assembly, and automatic temperature compensation is available for applications where it is required.

Features:

• Reliable performance in demanding applications
• Double junction prevents reference contamination
• Easy installation for various online monitoring sytems
• Suitable for use in a range of chemical environments
• One year limited warranty

• Ideal for measuring core temperatures in compost piles, hay, soil, or grains
• 3" diameter dial for easy reading
• Calibrate with external reset screw
• Thermometers meet ASME B40.3 standards for leak- and fog-proof operation
• Tips are 0.25" dia for fast response

AI3151 LabSen 241-3SP Glass-body Micro pH Electrode for Micro-Volume Solutions Containing Proteins by Apera

Backed by proprietary Swiss sensor technology and premium materials, LabSen 241-3SP Glass Micro pH Electrode is designed for micro-volume samples (≥30 microliters) containing proteins such as serum and microbiological samples. With the ultra-micro container (sold separately), it can test as low as 15 microliters.

Unique Glass Membrane – LabSen 241-3SP pH electrode adopts a micro cylindrical sensor tip (top end ø3mm, stainless steel ø4mm), making micro-sample pH testing easier than ever, and can be tested in high-temperature samples (up to 212°F). The stainless steel protective shaft ø4mm) ensures the durability of the slim glass tube.

Protelyte electrolyte – A specialized oily reference solution made for protein solutions and viscous samples.

Long-Life Reference System - composed of a glass tube, AgCl, and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of the reference system and extends the electrode's service life.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera Instruments MP500) to enable ATC or manually input temperature to achieve temperature compensation.
