Works well. I measured the output air temperature and it measured about 10% to 20% high. So 200 °C was close to 240 °C and 300 °C measured close to 360 °C. As I went to higher temperatures I noticed I was melting the protective cover near the thermocouple tip. After I cooked my thermocouple it seemed to be only 10% off. :-) :-/ Very happy with item. Heats up very fast, cools down decently fast. I like that when you shut it off it cools down to 100 °C before it shuts down. Air flow is decently adjustable It does not put out a lot of air flow but it is not meant to be a hair dryer. It puts out a decent amount for solder rework.

سؤال: What is max input voltage on channel 1-4 ??

السؤال بواسطة Bang00d على 2018-07-17 12:00:53

ebachalo According to the manual ( www-miniware-com-cn download la104-logic-analyzer-user-manual-v1-0 ) Input Voltage Range 0-5V (page 4) The hi-lo threshold seems to be user settable from 1.2 to 3V ( page 4 and page 14 )

Received in 10 business days (inculding Chinese new year) to Canada. What can I say. They are what they are. Look exactly as advertised. Preferred these to cheaper ones because thicker conductor. Don't think the insulation is silicone but fairly good quality.

Received in 10 business days to Canada (over Chinese New Years as well). Quickly tested the 5 samples with a 1S lipo against my decent voltmeter and charger: For the samples first reading is for all cells and second reading is for single cell Voltmeter 3.881V #1 3.8V 3.83V #2 3.8V 3.83V #3 3.8V 3.83V #4 3.8V 3.83V #5 3.8V 3.83V Voltmeter 3.881V (measured again at end) UP-S6 charger 3.86V Impressed that they all read the exact same, so guessing they were calibrated together or just that all have identical parts from same build batch. Since I have not calibrated my voltmeter I will not say for sure these are 0.05V off, but I trust my multimeter more. But 0.05V is quite accurate for the price. I would not expect better. The reverse voltage protection seems to work. Accidentally connected battery backwards first time with no problems.

Received in 10 business days to Canada (including Chinese New Years) You get what is shown. I tested with a low cost scale and values seem quite accurate. The two 20g measure 20.05g and 20.04g on cheap scale. The other values seem accurate. Don't have a laboratory quality scale to test. Case is nice and very handy to keep weights safe and clean.

Received in 10 business days to Canada (including Chinese New Years) Low priced, you get what you pay for. Connector wire is single solid wire with insulation. Wire is 0.2-0.3mm in diameter. Recommend for lower current use. Wouldn't use with higher amperage. Holds battery secure, difficult to get battery back out. Weight = 7.7g

Received in 10 business days to Canada (including Chinese New Years) Low priced, decent quality for the price. Connector wire is much better that the single battery holder. Connector wire is stranded, not single solid wire. I think could handle are few amps without problem. Highly recommend for the price. Holds batteries securely, not too hard to get batteries out. Weight = 14.5g

Received in 10 business days to Canada (over Chinese New Years as well). Tested and works as expected. No dark areas on el wire, all lit up uniformly. Pink wire looks like blue wire with pink out tube, when turned on it looks quite purple. The controller has a steady high frequency whine when on as expected, from more than 1 metre away it is hardly noticeable. EL wire is barely noticeable in bright sunlight,
