High-Performance; Colourless; 700 ml (24 fl oz) Koolance 702 series coolant is used by many industries requiring a high performance, low-toxicity, reliable coolant with corrosion and biological inhibitors. A high quality coolant is extremely important for addressing dissimilar metals and biologic growth (bacterial and algae) long-term. Koolance liquids will not clog components and can typically be used for 2-3 years before replacement is recommended. This container includes 700 ml (24 fl oz) of prediluted coolant and can function as a squirt bottle for convenient reservoir filling. It's recommended to replace the coolant at least every 2-3 years, or immediately if there is any change in color or clarity.The freezing point is -15°C (5°F). This coolant has been tested with the following materials: Metals: copper, brass, aluminum, stainless steel, nickel, steel, gold, lead Plastics: ABS, PA66, PBT, PE, PEI, PES, PETG, PMMA, POM, PP, PPE, PPO, PPS, PTFE, PU, PVC Rubber: EPDM NOTE: Not recommended for polycarbonate plastics or other PC-based plastics. Do you need a different colour? Koolance 702 ia available also in UV red or in UV blue (700 ml bottle, 5000 ml bulk container or 10000 ml bulk container).

The advanced and reliable circuitry of the HTC Series achieves 0.0009°C temperature stability. Its low profile package is ideal for designs with space constraints. The ultrastable linear, PI control loop offers maximum stability while the bipolar current source has been designed for higher efficiency. The HTC1500 drives up to 1.5 A for either Thermoelectrics (bipolar) or Resistive Heaters (unipolar). The HTC3000 drives up to ±3 A. An evaluation board simplifies prototyping: HTCEVALPCB. A heatsink that mounts directly to the HTC is available: HTCHTSK. The HTC1500 is designed for 0.031" thick printed circuit boards (PCBs). The HTC1500-62 is designed for 0.062" thick PCBs. The HTC Series temperature controllers are easily configured for any design. Virtually any type of temperature sensor can be used with the HTC and a built in sensor bias current source simplifies use with resistive temperature sensors. The independently adjustable Proportional Gain (P) and Integrator Time Constant (I) can be modified to optimize temperature overshoot and stability.Other features offer added flexibility. A single resistor sets the maximum output current to load. Add a diode to operate resistive heaters with a unipolar output current. An onboard reference voltage simplifies potentiometer control of the temperature setpoint. You can also choose to operate remotely with an external setpoint voltage. Two monitor pins provide access to the temperature setpoint voltage and the actual sensor voltage.The HTC1500 has proven reliable in such diverse fields as medical, defense, communications and manufacturing. The HTC is particularly suited to applications where temperature is scanned across ambient.
