98768-49 Traceable Lollipop™ Waterproof Thermometer Ultra with Calibration; ±0.4°C accuracy at tested points by Digi-Sense

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
• Stainless-steel probe is resistant to most laboratory chemicals
• One-key operation recalls MIN/MAX temperature readings
• °F/°C switchable
• Features enhanced accuracy

Includes

NIST-Traceable calibration certificate with data, probe cover with pocket clip, and battery.

AI235 5052 Compact Saltwater Salinity Pen by Apera

The Apera 5052 Saltwater Salinity Tester is designed for easy and reliable salinity measurements for aquariums, aquaculture, and environmental monitoring. Apera's unique platinum-coated sensor with automatic temperature compensation (ATC) ensures accuracy and precision of the measuring results in a wide range –an accuracy of ±1.5% of full range in 0 to 100 ppt (=100,000 ppm).

The dip-and-test is the easiest way to get reliable saltwater salinity readings (vs. hydrometers and refractometers). Sampling test is not required. Simply dip the meter into saltwater and get stable readings in 10 seconds. No need for rinsing between each test.

Say goodbye to frequent calibration. Calibrating the meter once every month will give you reliable results. The calibration solution is included in the kit.

The meter is designed with a single-button operation powered by 2*AAA batteries. Auto. Power-off and low-battery reminder functions are available.

Comes with a complete kit including the 5052 tester, 2 AAA Alkaline batteries, 50 MS/cm calibration solution, and a carrying case. 2-year warranty with the instrument and 6-month warranty with the sensor.

Note: The Apera 5052 tester measures practical salinity (NOT absolute salinity) converted from conductivity using The Practical Salinity Scale 1978 (PSS-78) and is standardized against the Normal Standard Seawater (S=35), which is accurately calibrated in conductivity ratio (K15). The PSS-78 is recommended by all oceanographic organizations as the scale in which to report salinity data.

• Dip and test - the easiest way to get reliable saltwater salinity readings (range: 0-100 ppt; accuracy:1.5% of full range)
• Apera's unique platinum-coated sensor with automatic temperature compensation (32 to 140°F) ensures accuracy and precision
• Standardized against the normal standard seawater (s = 35), accurately calibrated in conductivity ratio (K15) and in salinity
• Designed for saltwater aquariums, fish farms, and environmental monitoring
• Single-button easy operation. Calibration is only needed once a month

93623 1.25" Oxygen III Narrowband Filter by Celestron

The 1-1/4" OIII narrowband filter isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light. The result is extreme contrast between the black sky background and the faint photons of OIII light needed for detailed views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae, among other objects.

Each filter has an ultra hard, vacuum-deposited coating carefully designed to block all of the visual spectrum ranging from 400 to 700 nm This eliminates the un-natural colored halos surrounding bright stars common with O III filters of less sophisticated coating technology.
