Recently acquired a Apogee MQ-510 par meter and though I could be of some service to the locals here in San Diego. When I needed someone that owned one, no one was available nor did they owned one. Well if you need your tanks par reading let me know as I can service that measurement for a low and affordable cost to you or even a coral trade for my service if there is something that I like. Cost range is around $20-$30 depends on location, This will help fund my time and gas plus help those who may need my service. Its not a rental, I'll come to you and do all the measuring and we can create a par map for your reference also.
If you have any questions please let me know or contact me at 619-547-7057 to arrange a time to measure your par reading.
