94035 Smart DewHeater Controller 2X by Celestron

Work smarter, not harder, when it comes to combating dew. The Smart DewHeater and Controller 2x prolongs your battery life by optimizing power usage for up to two dew heaters. The controller gathers and analyzes information in real time to warm your optics just enough to prevent dew.

The Smart DewHeater and Controller comes with two ports to control two dew heaters at once. You can use one port to heat your optical tube while the other warms a second optical tube, a guide scope, an eyepiece, or another accessory. The controller also features an additional 12V DC output port so you can power another 12V DC device, such as your mount.

The Smart DewHeater and Controller works seamlessly with Celestron's Dew Heater Rings, which have a built-in thermistor to provide temperature readings of the corrector lens. Third-party dew heater bands or straps are also compatible; you simply need to add Celestron's Thermistor for Smart DewHeater Controllers (sold separately).

Smart Controls

At the heart of the controller is a powerful microprocessor that gathers information from the sensors, computes the data, and automatically adjusts your dew heaters. The controller monitors the ambient temperature and humidity using its integrated environmental sensor and monitors the heaters' temperatures using thermistors.

You can run the Smart DewHeater and Controller 2x as a standalone accessory. Or, if you want to view data from the controller and make manual adjustments, you can connect it to your Celestron telescope's hand control or your PC. The controller works with NexStar+ or StarSense hand controls running the latest firmware or Celestron CPWI telescope control software, included with every Celestron mount.

Power

The Smart DewHeater and Controller 2x runs on a 12V DC battery (like our PowerTank Lithium Pro or PowerTank 17) and can handle a maximum power of 120W (10A max current @ 12V DC). The controller also features a 12V DC output port. You can use this extra port to power another device, like your mount. This way, you can power your entire setup from a single source. Resettable electronic fuses prevent damage if input or output current draw becomes too high.

NOTE: If you are using two dew heaters in heavy dew conditions and powering a 12V DC device, the controller may be operating near its power limit. In this case, one PowerTank Lithium Pro or PowerTank 17Ah will not have enough capacity to run your setup all night; you'll need a larger capacity battery or multiple batteries.

Unique Industrial Design

The Smart DewHeater and Controller 2x features a heavy-duty metal housing. Inside, a cooling fan protects the controller's electronics.

The Bridge – On top of the controller, you will find the bridge, which is home to the device's status LEDs and environmental sensors. It also helps with cable management. We have positioned the temperature and humidity sensors here, away from the control box and other components that could generate heat. Unlike competitor products, our sensors do not require additional cables to obtain accurate readings.

The LED lights on the bridge indicate the device's current status. The LEDs provide warnings if the controller is drawing more current than your power source can supply or if the battery charge needs recharging. You can dim the lights if you are under dark skies.

Mounting – The Celestron Smart DewHeater and Controller 2x mounts on your CGE or CG-5 dovetail with the integrated dovetail clamps. If you prefer to mount the controller on your tripod leg, use the included strap.

Smart DewHeater and Controller 2x comes complete with:

• Smart DewHeater and Controller 2x
• Tripod leg strap
• Controller power cable
• Power cable for external 12V DC device
• AUX cable for connecting to Celestron mounts
• Thermistor extension cable to attach to Celestron's Dew Heater Ring

Enhance your setup

We highly recommend pairing this controller with Celestron Dew Heater Rings. They fit seamlessly on your Schmidt corrector lens and will improve your observing or imaging year-round.

For the highest level of dew prevention, we also suggest adding a dew shield to your setup. While not required, a dew shield will cut down on the amount of power the controller needs to provide to the dew heater rings to keep your optics clear.

• Using real-time data, the controller provides just enough heat to prevent dew from forming, prolonging battery life
• "Smart control" system monitors ambient temperature and humidity and adjusts power to the dew heaters automatically
• Compatible with Celestron Dew Heater Rings and third-party heating bands or straps (with thermistor accessory)
• Supports up to two dew heaters plus one additional 12V DC device, such as your mount
• Works with your Celestron telescope's hand control or CPWI telescope control software so you can view data and make manual adjustments
• Mounts securely to your telescope's dovetail or tripod leg
• Durable metal housing features an integrated cooling fan to protect the controller's electronics

SST1-M SST1 Single Gas Detector, CO 0-2000 ppm Serviceable - Real Time Display by WatchGas

The SST1 Serviceable offers one of the most cost-effective solutions on the market. With its 3-year replaceable battery and solid polymer sensor technology, the SST1 offers a compact and modular design without compromising its ruggedness. The SST1 Serviceable can be configured to your needs with one simple tap of the NFC and paired with the WatchGas Application. Monitoring for Low, High STEL, and TWA the SST1 will indicate any immediate risks and long-term exposure to toxic gases. SST1 is the platform that will allow us to expand on up to 8 different gases, so this is the ideal solution for your application.

Applications

• Oil and gas upstream
• Oil and gas downstream
• Contractors
• Site maintenance
• Turn arounds and shutdowns
• Boiler rooms
• Steel plants
• Laboratories
• Shipping
• Power generation
• Mining

Features and Benefits

• Easy Setup: Near Field Communication (NFC) is built in as standard and allows for a wide range of solutions depending on your needs. Simply pair with the WatchGas SST App to manage your fleet - bump, calibrate, assign or download event logs.
• Sensor: Using the latest in Solid Polymer Sensor Technology, our different target gases offer stability andreliability over extreme temperatures and conditions. With its smaller form factor and the removal of traditional Electrolyte, it is setting a new standard in the single gas market.
• Display: With the largest LCD in its category, the SST1's display shows the Real Time Gas Reading, TWA and STEL alarms. This allows for the user to make quicker decisions in a gas alarm environment. Bumper screens on either side of the LCD provide anti scratch protection ensuring the clearest of readings.
• Rugged: Designed with the harshest environments in mind, the SST1 offers an Ingress Protection rating of 67-68. The casing is a double shot housing that gives extra robustness while not compromising on quality. The screen protectors located on either side of the display are to protect the LCD from scratching and is required due to its smaller sensor profile.
• Alert: As a safety device it is essential that the device clearly notifies users of the presence of gas. The SST1 has a 95dB alarm at 30 centimetres which is the industry standard and is required in loud industrial environments. High and Low alarms can be configured by the customer and automatically updated directly on the device or through the SST Dock.
• Serviceable: The SST1 real time monitor is a cost efficient solution for users with STEL, TWA and real time requirements. SST1 real time allows users to replace battery and sensors to maximize the lifetime of the unit. Press and hold the button for 10 seconds to reset TWA/STEL for worker shift change.
