hanna instruments

[arnprior]

Does anybody here use the hanna instruments line of metering devices to measure water quality in their tank?I see they have several that will measure an array of parameters but do not know if they can be used in a reef enviroment.Or even if they will be accurate.The one I am looking at measures ph,tds,orp and temp.It is waterproof but made for the hydroponic industry.Do you think it will be safe to use in a reef tank?

They will owrked perfectly okay.

Some elctrodes do not last very long in continuous use, so .... just tell them you want electrodes rated for continuous use in salt water.

Thanks.They seem to be a lot cheaper than "aquarium"rated ones.
