people think of renting when something they need is expensive and they
are only likely to need it for a short period. However, there are many
other valid reasons for instrument hore.
Ashtead Technology is a specialist instrumentation company that has achieved
considerable success, not least because renting is often a better alternative
In recent years, the choice
of rented environmental instrumentation has been limited mainly to a small
number of manufacturers that offer renting as an alternative to purchase.
However, our experience shows that the provision of a renting service
involves a great deal more than just a financial alternative. Customers
demand fast access to the latest models, supplied tested and ready for
use, coupled with comprehensive technical support. We believe that a large
and growing market exists within the European environmental sector and
this is the reason for our investment in the Industrial Division and stockholding.
Whilst the demand for the latest
environmental technology is growing, the world is becoming smaller; instruments,
especially small hand held devices, can be shipped and delivered at a
moment’s notice almost anywhere in Europe.
The Rental Option
Most people buy equipment when they need it, but how many of us stop to
consider the renting alternative?
Let us suppose that you need
to be able to measure solvent emissions at various places in a paint factory,
but since this is not a frequent occurrence it seems logical to rent a
portable analyser. However, if you and your colleagues can find use for
this equipment every week, it might make more sense to buy the system.
So, this simple example demonstrates that the decision to rent is often
dictated by the frequency of intended use. However, there are a number
of other important advantages to renting.
For example, suppose the analyser
fails; you spend a couple of hours trying to fix it, give up and then
try and convince the manufacturer that it should replace it under warranty.
The right instrument
for every job
Let us also suppose that a colleague in a different department heard that
you had your own equipment, and asked if he could borrow it for use on
a different site, measuring different VOC’s. Will he look after
it properly and return it in its original condition? Is it the right analyser
for his application? Will he change the calibration? And will he return
it when he said he would?
In the following year, your
colleague calls again, and asks if you can bring your analyser to an important
site where they have a specific emissions problem. However, when you get
there you discover that this application requires a heated sample line.
So, your colleague hires another analyser and you are frustrated to discover
that monitoring technology has moved on since you made your purchase and
the hired model is far superior.
You would prefer the new model,
but having purchased the (now) older model, you either have storage issues
to contend with, or you have to find a form of environmentally acceptable
In all of these scenarios,
you would wish that you had rented rather than purchased your analyser.
If a rented machine malfunctions,
it is replaced quickly because the rental company is anxious that the
instrument performs to specification, so that you might rent it again.
Rented equipment is always delivered clean, checked, calibrated and ready
for use and if you had rented an analyser, it would have been delivered
to site on the prescribed day, at the right time.
Each time you rent an instrument, you have the opportunity to choose the
model that suits your application.
For example, there are several different types of VOC monitor, and it
is unlikely that it would be cost-effective to purchase all of them. For
example, PID’s are the most appropriate analysers for some applications
(contaminated land for example), whereas FID’s are more appropriate
for others (such as emissions monitoring). In some circumstances speciation
may be necessary, so an analyser with a gas chromatograph will be needed
and in a number of applications an intrinsically safe analyser may be
compulsory. The ability to choose the most appropriate model offers obvious
The same principles apply to
all types of environmental monitoring equipment, including for example;
toxic gas detectors, noise meters, contaminated land analysers, samplers
or water quality monitoring instruments.
Perhaps the most extensive users of rented environmental monitoring equipment
are consultants. There would be no sense in them purchasing a large range
of gas and water monitoring instruments, when they can simply include
the cost of renting in their proposals without taking on all of the disadvantages
The case for renting technical instruments is particularly strong because
they often require regular calibration which can be a costly, time-consuming
and skilled operation requiring specialised equipment. However, a good
rental company will often include calibration as part of the service,
so that instruments can be deployed immediately after delivery.
Financial case for
The strongest case for renting is of course financial. It is vitally important
to remember that the money used in equipment purchase could have been
used for something else. For example, if your organisation borrows money
and is paying say, 8% per annum, that means that the opportunity cost
of your purchase is 8%. If you had paid off that part of your loan you
would have saved the interest charge. Conversely, if you are in the happy
position of having no indebtedness, there is still the lost opportunity
of investing that money, either in your business, a Bank account, or another
Furthermore, your accounts department will depreciate the value of your
equipment over a period of 1 to 3 years in most cases, which means that
the cost of equipment with a purchase price of say €15,000 will actually
hit your bottom line by something between €6,000 and €15,000
in the first year.
The case for renting is stronger if the equipment is expensive to buy,
or you do not plan to use the equipment frequently. You should also consider
whether you could put the purchase money to better use.
You may also decide that the equipment requires skilled calibration, storage
and maintenance, coupled with specialist equipment, and the cost for this
would be preclusive.
You should choose to rent if you always need access to the latest technology,
or if you do not wish to bear the cost and inconvenience of storage, or
simply if you wish to ‘try before you buy’. Furthermore, global
environmental legislation is driving the need for an ever-widening variety
of environmental data, however, the availability of rental instruments
means that process operators are able to meet their monitoring requirements
without heavy capital costs.
