94054 Dew Heater Ring - 14" by Celestron

The Celestron Dew Heater Ring is the ideal dew prevention solution for your Celestron telescope. This must-have accessory will improve your observing or imaging nights year-round. The Dew Heater Ring permanently mounts to your 14" Celestron Schmidt-Cassegrain (manufactured 2006 or later), EdgeHD, and the 36cm RASA optical tube, replacing your retaining ring so you'll never be caught without it. The installation process is quick and easy (follow the manual for instructions).

How it works

The Dew Heater Ring replaces the retaining ring on your Schmidt corrector lens for efficient heating across the lens. The ring is constructed of lightweight, durable aluminum. Its rigid frame supports the cable circuity and the telescope's Schmidt corrector lens. Unlike other heating bands or strips that inefficiently heat the lens cell to warm the glass, the Celestron Dew Heater Ring heats the corrector glass directly, providing the most efficient transfer of heat to prevent dew formation.

Simply plug the ring into an external 12V DC power source for consistent, continuous heat that will prevent dew from forming even under heavy dew conditions. The Dew Heater Ring features two storage clips to keep the power and thermistor jacks secure when not in use while accommodating the telescope's dust cover.

The Dew Heater Ring also comes with a cable management clip that connects to the telescope's front cell. Corral the power and thermistor jack to prevent them from dangling and reduce unwanted pulls on the cable connection to the rings.

The Dew Heater Ring comes complete with:

• Dew Heater Ring
• Cable management clip
• Power jack extension cable
• Paper installation shield

Enhance your setup

To achieve the highest level of dew prevention while maximizing power efficiency, we strongly recommend pairing the Dew Heater Ring with a Smart DewHeater Controller (sold separately). The controller uses the ring's built-in thermistor and its internal environmental sensor to provide just the right amount of heat to the corrector to prevent dew based upon the ambient temperature, ambient humidity, and temperature of the Schmidt corrector, which can dramatically reduce the ring's power draw, greatly increasing battery life. The ring also includes an extension cable for connecting the ring directly to one of the controllers' heater output ports, or to a third-party controller's heater output port. (Note: the ring's integrated thermistor is only compatible with the Celestron Smart DewHeater Controllers).

We also recommend adding a dew shield to your setup. While not mandatory, a shield will cut down on the amount of power the Dew Heater Ring needs to keep the optics clear.

WD-17107-00 InnoCal NIST-Traceable Calibration; Hydrometer, 1-point by Oakton

All calibration certificates contain as-found and as-left data, estimated measurement uncertainties (emu's) and test uncertainty ratios (TUR's) at no additional cost!

NIST-traceable calibration allows you to confirm that the specific asset you purchase does in fact meet the manufacturer's published specification. Receive your product calibrated and ready to use rather than sending it to a third-party or internal calibration lab and incurring additional delays. EPA, USDA, ISO and GLP/GMP standards require regular NIST-Traceable calibration of all test equipment being used in critical applications.

• Provides traceability to NIST
• Lists the environmental conditions present at time of calibration
• Certificate lists actual values, uncertainties, and tolerances
• Regular calibration helps you meet ISO, EPA, GLPs/GMPs and other quality standards
• Not an accredited certificate

WD-17002-06 InnoCal NIST-Traceable Calibration, Thermistor Thermometer System Meter+Probe by Oakton

Regardless of the type of thermometry probe your application requires, InnoCal can ensure the accuracy of your meter, probe, or system!

All measurements reported are traceable to SI units via national standards maintained by NIST and performed in compliance with ANSI Z540, ISO17025 and MIL-STD-45662A. See the sample certificate under the "More Info" section to see how InnoCal's certificates provide more information in a concise manner than the rest of the industry.

InnoCal is accredited to ISO/IEC 17025 by the American Association for Laboratory Accreditation (A2LA) under certificate number 1746.01. This accreditation is your assurance that the calibration is performed in a qualified, controlled laboratory which is technically proficient and committed to quality and customer-focused continuous improvement. Our scope of A2LA accreditation can be found under the "More Info" section.

Calibrations on temperature systems (meter and probe) are performed using direct comparison in high-stability liquid using high-precision and SPRT's and displays. Measurements can be performed at four points between -196 and 1300°C. Points are generally selected at standard ITS-90 points across the range of the probe but customer-specified points can be accommodated. Calibrating the probe and meter together produces the highest accuracies.

• NIST-traceable calibration allows you to confirm that the specific asset you purchase does in fact meet the manufacturer's published specification EPA, USDA, ISO and GLP/GMPs standards require regular NIST-Traceable calibration of all test equipment being used in critical applications
• Receive your product calibrated and ready to use rather than sending it to a third-party or internal calibration lab and incurring additional delays
• For Thermistors only
• Calibration report is for both the meter and probe
• Calibration of the meter and probe is preferred over calibrating the meter and probe separately
