RF Oscillator Module, VCO 515MHz-1150MHz Voltage Controlled RF Oscillator Frequency Source Broadband Oscillator Module
[Strong compatibility]:For Yaesu FT-817/857/897 and other models for temperature-compensated crystal components, fully compatible with the original TCXO-9..
[High stability]:he frequency is 22.625MHz, which can improve the stability of the machine after replacing the original crystal. It is superior to the original module in different environments..
[High cost performance]:The price is only 15% of the original module, and the cost performance is extremely high..
[Effect is remarkable]:Actual test the frequency of the crystal is observed with a high-precision frequency meter. The original crystal frequency is deflected with a fire-baked , but this temperature-compensated crystal has no obvious change, and the effect is remarkable..
[Simple operation]:Turn off the power of the machine, open the cover of the machine, find the position where the temperature compensation crystal is installed. You need to unplug the ordinary crystal of the machine, then insert it according to the stitching of the machine. After installation, you can start using it without any settings..

FZONE 2.5L Aquarium CO2 Generator System Carbon Dioxide Reactor Kit with Regulator Mini DC Solenid and Diffuser for Aquarium Plants Tanks
PROFESSIONAL FULL CO2 DIY KIT! A complete system in 2.5L size bottle, that includes SUS304 stainless bottle, regulator, Mini DC solenoid, precision needle valve, CO2 Tubing, CO2 Diffuser and easy adjustable bubble counter.
SAFE! The bottle body is made of 1.5mm thick SUS304 stainless steel (25% thicker than normal 1.2mm bottle). It can sustain pressure up to 80kg/cm2(or 1137 PSI). Safety valve will open automatically when the inside pressure exceeds the safety threshold.
NEEDLE VALVE WITH BUBBLE COUNTER! High precision, aquarium specific needle valve provides accurate fine-tuning. Steady 1 bps is achievable. Bubble counter with check valve built-in. It stops water from back flowing into your CO2 tank (protects your CO2 tanks from rust and corrosion).
12V DC SOLENOID INCLUDED! Having the solenoid on a timer, you can specify when you want CO2 injection ON and for how long.
ATTENTIONS: Citric acid and sodium bicarbonate NOT included.
