The combo meter is a Guardian that you can carry from res to res. I use mine a dozen times a day. I've broken one in four years of continuous use.Depends on whether you want a continuous monitor (if you have one common res for a system) , or single bucket dwc.
Or soil for that matter, you weren't real specific.
I vote the guardian for continuous monitor. If you're checking individual buckets get the truncheon since bluelab is a very good name.
Fuckin' Hanna, LOL an EC pen that ISN'T WATERPROOF?! WTF are they thinking?I have a cheap £15 HM Digital off eBay and a BLT (Blue Lab Truncheon) both do same job, both match up. I calibrate the cheapo every 2 months or so in the recommended solution but never needed to do the BLT yet. You just put in solution and turn the little plastic screw until it reads 245 or whatever it is, reet simple imo. Truncheon is better as you can mix with it too
OH IT ISN@T WATERPROOF!!!!
Hanna has a factory here in in The Land Of Sticks, you can get one cheaper if I orderFuckin' Hanna, LOL an EC pen that ISN'T WATERPROOF?! WTF are they thinking?
With bluelab stuff calibrating ppm just means cleaning the probe until it matches the calibrating solution ppm.Here it is DB. http://www.amazon.com/gp/product/B00M19UR4W?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00 Stick in solution hold the set button and there is a calibrating screw on back.
Yes I've cleaned it per instructions. It still reads 250 ppm off. I've cleaned 10 times. Same result.With bluelab stuff calibrating ppm just means cleaning the probe until it matches the calibrating solution ppm.
I said anything about the Truncheon (I can even spell it). I am saying a decent meter does a great job for 90% of people smart enough to know how to use them. It is obviously a skill we don't all share. As evidenced by your post. Thanks for writing.lol you have stock in Hannah? I'm sorry if me saying the higher end Tungeon is better that that shit meter you own, perhaps if you had a real meter you could dial your shit in, grow some dank and afford a real ppm.
Hanna Primos. Use the money you save for other supplies. But like I said to another poster the user MUST be smarter than the instrument they are holding. This goes for Blue Labs as well.I need one and i am on the lower end of middle class lol so i am ass broke most times.......which would you rec in soils/soiless?
It's recommend you change it out every 6 monthsThe only time I replace a pH probe is when I drop it. Otherwise my Blue Lab combo meter is faultless. This is why I recommend it; it just works.
