LabSen 553 Plastic Combination Spear pH/Temp. Electrode by Apera

Backed by proprietary Swiss sensor technology and materials, the LabSen® 553 3-in-1 pH/Temp. Spear Electrode/Sensor/Tester is designed for testing soil directly (This is a replacement probe for Apera PH850-SL, PH9500-SL).

Long-Life Reference System - The LabSen 553 pH electrode adopts a long-life reference system, which is 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 reference electrode and extends the service life of the electrode.

Polymer Electrolyte - The solid polymer electrolyte makes the electrode hard to be contaminated and maintenance-free.

Special Glass Membrane - The LabSen 553 pH electrode adopts a spear sensor tip, which is ideal for directly testing semi-solid samples like soil.

Compatible Apera Instruments' meters: PH700, SX823-B, MP511, PH800, PC800. May NOT work with other brands' meters because the temperature unit might be incompatible. The electrode is backed up with a 6-month warranty by Apera Instruments.

• Proprietary pH sensor technology and materials from Switzerland
• Special LabSen Spear pH sensor tip, ideal for direct soil pH testing. No more slurry making.
• Pom housing, ideal for use in harsh environments
• Polymer electrolyte - not more clogged junction
• Long-life reference system, improving the stability of reference electrode and prolong the service life of the electrode

08084-09 TI.30 12 Silicone Filled Back-Con Bimetal Thermometer, 3" Dial, 12" L/25-125F/-5-50C by Digi-Sense

Accuracy is ±1% full-scale when stem is immersed 2" in liquids or 4" in gases (immerse models with a 2.5" stem length 2" in gases).

Measured stem length from the top of the threads to the bottom tip of the stem. Stem dia is 0.25"; threaded connection is 1/2" NPT(M). All thermometers meet or exceed ASME B40.3 standards. Maximum environmental temperature for Acrylic lens thermometers is 200°F (93°C).

Key Features

• Dampened movement
• Anti-parallax dial for accurate readings
• Hermetically sealed per ASME B40.3 standard to prevent fogging and protect against tough environments
• Rugged 304 stainless steel construction with Acrylic lens
• Recalibrate using the external reset screw
• For use in applications that do not exceeding 200°F

Part Number: J1011100PM1

18526-57 Type J Flat-Leaf Thermocouople Probe, with Mini-Connector, 4.5" L, 5ft Coil Cord by Digi-Sense

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).

• Ideal for measuring in hard to reach spaces due to a flexible tip
• Designed for extremely fast response due to the low mass but yet more durable than other miniature diameter probes (.035" thick at tip)
• Response Time: .75 seconds or greater
• Each probe comes with a color coded ANSI coiled cable: type J-black, type K-yellow, type T-blue, and type E-purple.
• Custom designs or changes to this product are available upon request

AI3103 LabSen 241-6 Glass-body pH Electrode for Small Samples (>0.2mL) by Apera

Built with proprietary sensor technology and premium materials from Switzerland, LabSen 241-6 Glass-body Semi-Micro pH Electrode is designed for test tubes and small-volume samples (>0.2mL).

LabSen S-type semi-micro glass membrane - 100mm in length and 6mm in diameter, low membrane resistance (<350MΩ), making reliable small-volume (>0.2mL) pH measurement easier than ever, and can be tested in high-temperature samples (up to 212°F).

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.

• Proprietary pH sensor technology and premium materials from Switzerland
• Low-resistance LabSen semi-micro cylindrical glass membrane, suitable for test tubes and small samples (>0.2mL)
• Smallest test volume is 60µL with the use of the semi-micro container (sold separately)
• Long-Life Reference System, improving the stability of the reference and extends the electrode's service life
• No more air bubbles inside the glass membrane thanks to the Swiss blue gel electrolyte.

874307 Chemcassette Tape, Phosgene by Honeywell Analytics

Chemcassette® is the unique trademarked name for a calibration free toxic gas detection method that uses an optical scanning system to detect the presence of gas by a colour change on the specially chemically impregnated paper tape. Chemcassette® technology is highly specific and reacts extremely fast to the presence of parts per billion (ppb) levels of many hazardous gases. Over 200,000 points of gas detection are currently maintained by the Chemcassette® sensing technology at any given time around the World in some of the most critical safety applications possible.

Each Chemcassette® is manufactured to traceable ISO 9000 manufacturing standards by a world class team of highly trained chemists and each batch is calibrated with ultra pure gas that is traceable to nationally accepted standards. This means that the end user does not have to provide calibration facilities themselves thereby saving cost and reducing risks to their own staff.

Efficient high volume manufacturing techniques means that there is always available Chemcassette® in stock that can be shipped anywhere in the World so that our customers are never left without adequate safety cover. Application support with expert gas detection chemists is available by phone and e-mail and is supported with many years of technical application notes and help to diagnose common support issues.

Should there be any concern regarding the performance of an individual Chemcassette®, a free of charge evaluation will be performed to trouble shoot the observed scenario using the award winning quality management system "Customer Discrepancy Report" CDR. Every CDR completed by a customer is guaranteed a full response and the outcome is reported directly back to the end user to ensure a complete resolution process.

Each Chemcassette® is backed with a full warranty and we have over 20 years of experience regarding the quality control of our proven sensing technology.

Additional Features and Benefits:

• Visible proof of a gas release event
• Greater sensitivity (detection down to parts per billion levels)
• Superior selectivity (less cross-interference with other gases)
• Fast response time
• Low false alarm occurrence
• Stability (consistent, repeatable operation)
• No calibration required
• Easy to use
• Available in fixed and portable instrumentation
