94460-46 Traceable Memory-Loc™ Datalogging Thermometer with Calibration; 2 Stainless Steel Probes by Digi-Sense

Easily monitor temperatures overnight or for any time period - stores over 1 million temperature observations. Datalogger will stop recording when storage is full and will not overwrite recorded data. Memory can be cleared after downloading data and alarm events. 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 include 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. Unit continues to record data while downloading data. Sampling rate is 5 sec (10 sec for models 98768-55, -56, -59, and -60). Select logging interval ranging from 1 min to 24 hours. Other status indicators include low-battery, memory full, USB data transfer, and active alarm state. Probe is attached to a 10-ft (3 m) microcable that permits a door to close on it. Mount meter with included hook-and-loop strips, wall-mount slots, or use flip-open stand on benchtop.

Select from glycol-filled glass, or vaccine bottle probe(s), standard plastic Bullet™ probe(s), or stainless steel probe(s). Bottle probes contain nontoxic glycol solution which is considered GRAS (generally recognized as safe) by the FDA. The solution filled bottle simulates the temperature of other stored liquids and eliminates the rapid temperature fluctuation caused by opening the refrigerator/freezer door. Vaccine bottles are designed to fit vaccine trays. Use standard Bullet probe to measure air and liquid temperatures. Bullet probe sensor and cable may be completely immersed; sensor measures 3/4"L x 0.187" dia (19 x 4.75 mm). Durable stainless steel probes measure 6-1/4"L x 0.125" dia (159 x 3.18 mm) and withstand both low and high temperatures - ideal for measuring temperatures of air, liquids, and semi-solids.

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.

Thermometer features 2 stainless steel probes.

Key Features

• Store up to 10 unique alarm events, memory can be cleared after downloading data

S650CD pH Sensor, Flat, CPVC, Submersion by Sensorex

The submersion pH and ORP electrodes from Sensorex are designed for measurements in tanks, flumes and sewer lines. Submersion designs are are also well suited for applications with high suspended solids or where flocculation operations require low velocities or in tanks with high agitation.

Where low velocities are present and coating is a problem, the electrode can be mounted at a 45 degree angle facing into the flow so as to obtain increased scrubbing action across the measuring surface.

The cartridge quick disconnect design makes changing electrodes a snap and minimizes down time due to electrode maintenance.

Model S651CD offers pH glass protection feature and the extra performance of acrylamide reference gel.

• Quick Disconnect Design Saves Time and Money
• Installs in Seconds, No Tools Needed
• Flat Surface Design Resists Coating
• CPVC or PVDF Models Available
• Available with or without ATC Elements

S350CDHF pH Sensor, Flat, Polymer, 12mm, HF by Sensorex

The specification sheet serves as an addendum to the pH LabSpecs sheet and covers all lab pH electrodes suitable for use in hydrofluoric acid.

Specifications differences for use in hydrofluoric acid (HF) are shown in SPECIFICATIONS section below. Please note 2 major differences as compared to standard electrodes. First, pH range is 0-12 not 0-14. Second, the temperature range is 0-50 deg C.

This series of electrodes are compatible with any lab or portable pH meter. Calibration of these electrodes is as normal with any standard pH electrode using standard pH buffer solutions.

• Resist attack and etching from HF (up to 2% v/v)
• Resist coating and fouling
• Compatible with any pH meter
